Molybdenum Piercing Plug for Piercing Seamless Steel Pipes

Seamless steel pipes are known as the “blood vessels” of industry and are important raw materials for national industrial construction and national defense construction, while piercing plugs made of molybdenum alloy are the most efficient tools for them. 

Whether manufacturing airplanes, ships, trains, automobiles, boilers, power stations, or transporting oil, steam, water, or developing mineral deposits for geological drilling, seamless steel pipes are required and inseparable. It can be said that the development of many industries such as petroleum, chemical, steel, machinery, military, aerospace and other industries can not be moved forward without seamless steel pipes. 

There are many kinds of seamless steel pipes and their production methods are also various. At present, the production lines for hot-rolled seamless pipes mainly include automatic pipe rolling mills, continuous pipe rolling mills, periodic pipe rolling mills, three-roll pipe rolling mills, pipe jacking mills and extruded steel pipe mills.

However, regardless of the production method, the decisive factor for product performance is molybdenum piercing plug. This material of plug is the most efficient perforated plug, which guarantees the good performance of seamless steel pipes.

Molybdenum piercing plug is also named molybdenum piercing mandrel, which is made of zirconium titanium molybdenum (TZM) alloy material. To pierce stainless steel pipes, the plugs must withstand high temperature and high stress. Molybdenum is one of the rare metals with characteristics of high melting point, excellent mechanical features, corrosion resistance and easy workability. The recrystallization at high temperatures produces a reduction of its mechanical properties such as UTS, hardness and toughness. 

This reduction of the properties of pure molybdenum can be reduced by small additions of elements such as zirconium, titanium, boron and rare earth which increase the recrystallization temperatures and therefore the mechanical properties of such molybdenum alloys.

TZM is a kind of molybdenum alloy, which contains small amounts of titanium, zirconium and carbon. The piercing plug made of TZM material can extend its service life and improve the utilization rate.

Molybdenum Electrodes Are Resistant to High Temperature During Glass Melting

Molybdenum metal is an indispensable material in glass melting applications. Its unique chemical properties, metal properties, mechanical and physical properties enable manufactures to produce high-quality molybdenum electrodes for glass melting. 

Globally, molybdenum electrodes have been widely used in glass melting for many years, but the specific requirements for molybdenum electrodes used in glass melting and the understanding of its high-temperature processing technology have not yet been popularized. There are two producing processes - traditional powder metallurgy and the unique electron beam melting method (EB method). The purity of the molybdenum electrode ≥99.95%. 

Although moly electrode is extremely resistant to high temperature and high in strength, it is also extremely easy to be oxidized at high temperature.

During glass melting, the molybdenum electrode starts to oxidize at 400°C, accelerates oxidation at 600°C, and oxidizes rapidly above 700°C and then produce MoO3. MoO3 is a volatile oxide that does not protect the electrode. Finally, the molybdenum will be corroded. Therefore, the molybdenum electrode exposed to the glass must be cooled to keep the temperature below 400°C, or to avoid contact with oxygen in the air.

When designing and using the electrode water jacket, it must be noted that at temperatures above 500°C, molybdenum will quickly be corroded in the air to generate easily volatile MoO3, so the molybdenum electrode should be equipped with a cooling water jacket in the glass melting.

Fortunately, the molybdenum electrode does not chemically react with the molten glass, and does not cause staining to the molten glass. A small amount of molybdenum is dissolved as an oxide in the glass melt, which will make the soda lime glass slightly yellow, but it is usually very slight. Therefore, it has no effect even on colorless glass. The molten glass with poor reducibility has much less corrosive effect on the molybdenum electrode than the molten glass with oxidizing properties.

How Cooling Water Jacket Prevent Glass Melting Electrode from Oxidation?

Molybdenum electrodes are widely used in melting furnaces for glass and glass fiber production, with the advantages of low energy consumption, long working life and high quality of finished products. 

Molybdenum material will not be corroded in the molten glass due to its high melting point and its reaction with glass solutions is too small to affect the color of finished glasses. Therefore, moly electrode is deeply loved with enterprises all over the world. 

However, the glass melting electrode has some defects despite of so many charming characteristics. The most important one to be noted is that molybdenum metal will oxide when the working temperature is higher than 400℃, and will start to produce MoO3 when the temperature is higher than 700℃. In order to avoid oxidation, electrode cooling water jacket is introduced that can enable glass melting safely and stably.

The cooling water jacket is an important device to protect the electrode from oxidation, and it is also the most problematic part of the electric melting furnace. Its front end is often at a temperature of about 1100°C, while the cold end outside the furnace is about 50°C. The glass liquid penetrates into the hole of the electrode to wrap the electrode to prevent the aluminum rod with high temperature from being oxidized. At the same time, the glass solidified in water freezes the electrode onto the electrode. It is difficult for electrode to be oxidized because its cold end is at temperature below 500 ℃.

In conclusion, the functions that the electrode cooling water jacket should play are as follows:

1. Able to fix the molybdenum electrode in the required place; 

2. Protecting the part of electrode that is not covered by molten glass from oxidation, and cool the temperature to below 400℃;

3. Preventing the inserted part of electrode from being damaged due to the high temperature and the electric current entering the molten glass prematurely during the heating process.

How to Balance the Diameter and Current Density of Molybdenum Glass Melting Electrode?

Molybdenum is the ideal material for glass melting electrodes due to its good electrical and thermal conductivity, excellent corrosion and creep resistance. Generally, the diameter of electrode ranges from 10mm to 120mm, which is mainly depended on the current density.

To melt borosilicate glass, the most common diameter of electrode is 50mm. When the current density ranges between 0.42 A/cm2 and 0.49A/cm2, the electrodes do not need to be moved forward as they have no consumption. For vertical electrodes, whether the electrode to be continued in the furnace required to be evaluated when the density value reaches 0.8A/cm2. 

For electric furnaces with a long furnace age (more than 4 years), the current density increases as the electrode is consumed. If the electrode is not ready to continue, the current density needs to be controlled at a lower value. Normally, there is little consumption for moly electrode when the current density runs below 0.6A/cm. 

When molybdenum glass melting electrode is used to smelt soda lime glass and other low-resistance glasses that have a resistivity lower than 15Ω·cm, it is difficult to control the current density below 0.6A/cm2 because of its low viscosity and low resistivity. Therefore, electrodes with φ75mm diameter are often used. In addition, the electrodes will also have different degrees of loss during operation, so the electrodes must be made continuous. From the perspective of operating cost, the plate electrode consumes less and is more suitable for electrofusion of soda lime glass.

The conductive distance of the electrode has a direct impact on the service life of moly electrode. If the distance is too close, it will be in a low-voltage and high-current state during operation. This local high power will not only reduce the life of refractory materials, but also increase the electrode loss and bring defects to the product. In addition, if the current density value is too large, the destructive effect on the electrode will be even greater. Within the allowable range of voltage that the electric melting furnace can withstand, the high-voltage and low-current operation scheme can improve efficiency on conditions that it must meet the requirements of melting process and operational safety.

Molybdenum Disulfide Enables Good Lubrication for Carbon Motor Brushes

The brush is a kind of conductive component that plays an important role in sending electrical current between motionless and rotating parts by sliding contact. Due to its good electrical, thermal and lubricating properties as well as a certain mechanical strength and the instinct to inhibit commutation sparks, all most all DC motors and commutation motors use brushes. Typical applications include electric motors, alternators and electric generators.

Since the performance of the brush has significant impact of the performance of rotating machine, the choice of brush is a critical factor. Usually, carbon motor brushes have special requirements for resistivity and contact resistance, and requires good sliding contact characteristics such as friction coefficient, wear resistance. 

Molybdenum disulfide (MoS2) is the most famous of the single layer transition metal dichalcogenide (TMD) family. It has been used in bulk for many years as a solid state lubricant, this is due to its low coefficient of friction in addition to its high chemical and thermal stability. MoS2 can maintain a very good lubrication effect in mechanical parts that operate in vacuum. 

When the brush contains a certain amount of molybdenum disulfide. Although it is difficult to form a cuprous oxide film at high altitude, it can form a sulfide film with good lubricating effect. This film is tightly adsorbed on the surface of the slip ring, so that the brush still has good lubricating performance at high altitude. In addition, molybdenum disulfide has good water resistance and pressure resistance.

Molybdenum disulfide is also an ideal solid lubricating material in the aerospace field. It has a very low friction coefficient and a high yield strength. Therefore, combining the characteristics of the two, the development of a silver-based brush composite material with high conductivity, low friction factor and good mechanical properties is an urgent need for electrical contact components in the aerospace industry.

Chinatungsten online produces professional molybdenum disulfide that is suitable for the electric brush industry, strictly controlling the particle size, water, acid value and other indicators. Our MoS2 can be for a variety of customer needs and purposes.

Molybdenum Alloy Plugs to Pierce Stainless Steel Pipes

There are two kinds of steel pipes – stainless steel pipes and welded steel pipes, according to their production methods. Compared with welded steel pipes and other steels, stainless steel pipes are pierced with tools such as plugs and mandrels.

These piercing tools not only participate deformation, but also are the most important factors that determine whether the main processers of steel pipe production, such as piercing and pipe rolling can operate normally. As a matter of fact, the production process of seamless steel pipe also reflects the technical level of these tools. In other words, the research on internal deformation tools is an important subject of seamless steel pipe technology research.

Molybdenum alloy plugs are used to pierce seamless tubes of different materials, such as stainless steel, brazing steel, high-temperature alloy steel and other special parts. As they work in high temperature and harsh environments, the material of plug requires the characteristics of high temperature strength, high temperature oxidation resistance, long service life, corrosion resistance and not easy to stain glass.

Therefore, the material of the plug usually adopts molybdenum alloy with a composition of Ti, Zr, C and Mo. Molybdenum alloy plug is produced in a powder metallurgy process, has a higher recrystallisation temperature and higher strength compared to pure molybdenum, and is readily deformable even at room temperature. These effects are due to mixed crystal formation between Mo and Ti as well as the precipitation of ZrC as a dispersoid.

Actually, the materials to be used depends on what kinds of steel pipes to be pierced. Different materials of pipes have different characteristics and thus require plugs to meet different working conditions. As a professional manufacturer of molybdenum and tungsten, Chinatungsten Online can offer you various kinds of piercing plug. Certainly, customized designs are welcomed. Send us drawings and inform us its detailed application, we will offer you the best solution.

Amazing! 500 Bottle Caps Produced in One Minute with Hot Runner System

 500 plastic cups or 500 bottle caps are produced in one minute. Oh my god, it’s so amazing! Indeed, it is probably a fantasy to achieve such high efficiency with traditional production lines. But hot runner system has achieved and is constantly improved at present. 

Almost every industry, including construction, electronics, aviation, automotive, medical, food and beverage, more realizes the potential for gaining a competitive advantage. Injection molding is not only an efficient method of manufacturing precise plastic parts and components, but also reduces production time, has high precision and reduces material waste. It can produce plastic parts that are as strong as steel, or can be very soft and flexible.

When using the plastic injection molding process, the manufacture of any part starts with the mold. The molding system is divided into two categories: hot runner molds and cold runner molds. The hot runner uses a screw nozzle, which is fed by a pump through the barrel, while the cold runner uses a closed thermosetting mold. The main task of any runner system is to guide the plastic melt from the runner to the mold cavity. 

The system requires additional pressure to push the material through the flow channel. The frictional heat generated by the material in the runner mold flows through the runner and increases the temperature, thereby facilitating the flow. One of the best rewards of any project is to reasonably determine the size of the runner for a given component and mold design.

The nozzle is the key component of the hot runner mold. In the hot runner system, in order to maintain the molten state of the plastic in the nozzle, heat insulation must be as perfect as possible, and some nozzles need to be heated internally or externally, while the cavity needs to be cooled. The temperature difference between the two is usually 100~200℃. Therefore, the material and design of nuzzle should meet the thermal balance requirements in priority, which are necessary to avoid too much cold material in the nozzle to solidify and block, but also to avoid overheating of the plastic, casting or drawing, or even decomposition.

The best material for machining nuzzles is titanium-zirconium-molybdenum alloy (TZM alloy). TZM nuzzle can maximize the utilization of materials and meet the requirements of plastic melt insulation and heating. In addition, molybdenum alloy nuzzle also has a very long service life, which can greatly reduce production costs. 

Chinatungsten Online is a very professional manufacturer of tungsten and molybdenum, with rich experience in the production of titanium-zirconium-molybdenum alloy rods. If you have any purchasing plan, please feel free to contact us.

Molybdenum Disulfide Is One of the Ideal Materials for Transistors and Chips

Molybdenum disulfide (MoS2) is considered to be the most promising alternative to silicon due to its unique single-layer atomic structure and excellent photoelectric properties, and becomes one of the ideal materials for future applications in high-precision technology fields such as semiconductors, transistors, and chips. Therefore, in recent years, scientists have maintained a strong interest in the exploration and research of molybdenum disulfide.

Recently, the EPFL research team used molybdenum disulfide to develop a new type of "brain-like neuron transmission" computer chip, which has the ability to process and store information in the same circuit, and realize small size for computer equipment. It provides new ideas for optimization, high efficiency and energy saving.

Molybdenum disulfide is a transition metal chalcogenide two-dimensional material (TMDC). It has a graphene-like layered structure and has the characteristics of a direct band gap semiconductor that graphene does not have. Molybdenum disulfide is composed of three atomic plane layers (S-Mo-S) stacked. It has a large specific surface area, high electron migration rate, anti-magnetic resistance to radiation, low energy consumption, environmental protection, energy saving and efficiency, and high stability. And can achieve large-scale production, is an ideal material for optical and electronic equipment.

For the first time, EPFL researchers have successfully applied the two-dimensional material molybdenum disulfide to a chip that integrates data storage and logic operations. This will subvert the traditional computer model of processing data by the central processing unit (CPU) and then transmitting it to the hard disk for storage. 

According to reports, the new chips are based on floating gate field effect transistors (FGFETs) and are usually used in flash memory systems for cameras, mobile phones or computer equipment. These transistors can hold charge for a long time, and molybdenum disulfide with a thickness of only three atomic layers can not only further reduce the volume of electronic devices, but also has a strong sensitivity to the charge stored in the transistor, so logic operations can be implemented as well as data storage function.

Chinatungsten Online's molybdenum disulfide not only has great application potential in optical and electronic fields such as semiconductors and nano-transistors, but also can be used as lubricants, antioxidants, catalysts, etc., and is widely used in aviation, automobiles, mining, shipbuilding, bearings and other industrial fields.

Nuzzle Tip, Machined from TZM Rod, Is Essential for Hot Runner System

HRSflow is completing the expansion of its 3,000-square-meter factory in San Polo di Piave, Italy. The expansion was designed according to lean production standards to make the hot runner assembly process more efficient. The goal is to ensure increased production capacity and provide customers with greater flexibility.

Since its introduction into the industry, hot runners have played a key role in improving the injection molding process. Although the capital cost is greater than that of cold runners, its ultra-high production efficiency makes it a long-term and economical choice. The improvement of system performance can produce parts with excellent appearance and increase part functions. In addition, the hot runner improves energy efficiency and saves plastic raw materials, thereby shortening cycle time and reducing part costs.

Companies in the world are implementing hot runners and seeking various solutions for further optimization considering its advantages. Of course, the focus of this article is not on this, but on one of the important parts- hot runner nuzzle tip. 

A hot runner system is an assembly of heated components used in plastic injection molds that inject molten plastic into the cavities of the mold. The used nozzle material is important as it affects production efficiency of the whole system, production cost and quality of finished plastic products. 

Pure molybdenum has a very high melting point, good strength, low thermal expansion coefficient and excellent thermal conductivity, and is a good comprehensive candidate material for most high-temperature applications. TZM is an acronym for "Titanium-Zirconium-Molybdenum", which is a molybdenum alloy. Its production method is powder metallurgy.

Although TZM is 25% more expensive than pure molybdenum, in some applications, the additional cost is offset by its increased strength at high temperatures. The recrystallization temperature of TZM is higher than that of pure molybdenum, which reduces the possibility of embrittlement at high temperatures. In high temperature applications, TZM has higher strength, hardness, creep resistance and ductility, which can ensure that it will not weaken or become soft.

Therefore, titanium-zirconium-molybdenum alloy is the most suitable material for nozzles at present. Chinatungsten Online is known for its high-quality products, outstanding service and attention to detail. The provided TZM rod has strict tolerance control and high processing yield.

How MoS2 Improves Energy Storage Capacity in Lithium-ion Battery

In the development of sustainable technologies such as renewable energy and electric vehicles, the storage of electrical energy is as important as power generation. How to improve battery performance is a research field of great scientific significance. A large number of studies have shown that molybdenum disulfide (MoS2) composite materials play a key role in improving battery power, energy storage capacity, charging speed and stability.

As we all know, lithium-ion batteries are everywhere, from mobile phones to electric vehicle, thanks to its advantages of environmental protection, small size, light weight and no memory effect, but this does not mean the battery does not have any shortcomings. Actually, lithium-ion batteries have not been widely used in aviation, navigation and national defense due to their low energy density and high safety risks.

As a representative material for the negative electrode of commercial lithium-ion battery, graphite has good stability and conductivity, but it cannot store too much lithium ions between layers, thus significantly reducing the capacity of the battery. Normally, the more active lithium ions stored in the electrode, the greater the capacity of the battery. In addition, the battery can get higher efficiency if lithium ion diffusion rate can be faster. 

But researchers have found that MoS2 can be used to replace graphite anodes to improve the energy storage capacity.

MoS2 is a two-dimensional layered material with a naturally adjustable band gap. Its unique properties have attracted the attention of scientific researchers and have important application prospects in the fields of microelectronics, optoelectronics and batteries. Its wider interlayer spacing makes its storage capacity nearly twice that of graphite.

New research shows that MoS2 can also play a role in the development of next-generation battery technologies including Li-O2 (air) and sodium ion batteries. Although these technologies have not yet been commercialized, electrodes using MoS2 or MoS2/graphene composites have shown excellent performance in laboratory tests. In sodium ion batteries, the wider interlayer spacing of MoS2 than graphite is essential to accommodate larger Na+ ions. Besides that, the storage capacity of sodium-ion batteries with composite electrodes is higher than the combined battery capacity of MoS2 and graphene electrodes alone.

The challenge of battery technology is the need to store more electrical energy, provide more electrical energy, and be able to charge faster. The results from laboratory show that MoS2 can play a role in the future battery economy. With the development of large-scale manufacturing processes, MoS2 composite electrodes are expected to play an important role in meeting the challenges of energy storage.

Molybdenum Disulfide Is Used in Brake Pad as an Anti-friction Additive

 As a good anti-friction additive, molybdenum disulfide (MoS2) is essential for producing brake pads. The composition of raw materials of brake pads includes four parts: binder, reinforcing fiber, friction performance modifier, and filler. 

There are two type of friction performance modifier. The first one is anti-friction materials. Its addition can improve the friction resistance of the material, reduce noise and friction coefficient. Graphite, molybdenum disulfide, lead, and copper belong to the material. The second one is frictional materials. Its addition can increase the friction coefficient of the material. Most inorganic fillers, some metals and their oxides are included in this category. The friction performance modifier mainly adjusts the thermal stability of the material and its working stability.

MoS2 has advantages of good dispersion, wear resistance and noise reduction, which is widely used in many fields. Its performances in the brake pad as a friction modifier additive as following: 

A.Friction reduction

The regular particle size of MoS2 is 1.1-30 μm with 0.04-0.06 friction coefficient and excellent dispersion to make sure good friction reduction. 

B.Friction enhancement

When the friction temperature of friction material increases sharply, molybdenum disulfide oxidizes to form molybdenum trioxide, which expands with the increase of air temperature and then increases friction.

C.Oxidation resistance and anti shedding

Molybdenum disulfide is slightly acidic. It covers the surface of friction materials to protect other materials from oxidation, so that it is not easy to fall off and has strong adhesion.

D.Expansion

When the friction material is in the high-temperature state of braking, many low-temperature materials such as fillers and resins are easy to be carbonized and burned out, resulting in the increase of internal voids of the materials, while molybdenum trioxide can better make up for it.

E.Reduce the specific gravity

The specific gravity of MoS2 crystal is 4.5-5.2. With the increase of fineness, the specific surface area also increases, and the specific gravity decreases, which reduces the weight of brake pad to a certain extent.

How to Improve the Performance of Molybdenum Glass Melting Electrodes (GME)

The molybdenum has been the best material of electrode for melting high-grade optical glass, glass fiber and refractory rock wool for many years thanks to its advantages of high melting point (2620℃), good conductivity and thermal conductivity, small expansion coefficient, high temperature strength and good resistance to glass corrosion.

However, molybdenum is easy to oxide in oxidizing atmosphere at high temperature, and it will be lost due to the intergranular corrosion of glass liquid on electrode surface. Therefore, it is a common concern to improve the quality and performance of molybdenum glass melting electrodes (GME).

1. Production technology control of moly electrode

Ammonium molybdate is heated to obtain molybdenum trioxide; moly trioxide is reduced to molybdenum powder by hydrogen heating; molybdenum powder to form bank electrode in molds under isostatic pressing equipment; the blank electrode to be sintered, forged and machined into finished products.

2. Control of impurity content

The production of moly electrode requires high-quality molybdenum powder. Impurities will cause cracks or hidden cracks of electrode; C and N contents will cause bubbles in the glass liquid, which will affect the quality of finished glass; metal elements such as Ti, Ni, Cu, CD will make the glass colored.

3. Control of molybdenum powder particle size

It is concluded that the molybdenum powder with medium particles and close to normal distribution is the best material for producing high-quality molybdenum electrode products, according to the production experience and data analysis.

4. Sintering of moly electrode

In order to reduce the temperature difference between inside and outside of blank molybdenum electrode, slow and smooth temperature rise and stage heat preservation system are adopted to prevent hidden cracks caused by excessive thermal stress. Appropriate holding temperature and holding time can ensure fine and uniform grain structure.

5. Forging of moly electrode

Adopting appropriate forging process, especially appropriate forging temperature, final forging temperature, deformation and deformation.

Wear-resistant Nozzle: TZM Rods for Plastic Injection Molding

Manufacturers of plastic components or tool manufacturers of such components represent a growing market. More companies need more and more types and larger quantities of plastic materials in the industrial field. In 2019 the operating income of China's 15,835 enterprises above designated size was 1,907.748 billion yuan, and this figure continues to rise.

Along with this growing demand, requirements for materials and their performance are also increasing. Plastic manufacturers demand maximum strength for materials. This is why glass and carbon fibers can be integrated into the material to reinforce the particles. In order to improve fire resistance, highly corrosive flame retardants are also used. Therefore, all components in contact with the plastic injection molding must have maximum wear resistance and corrosion resistance! Only in this way can maintenance be minimized during the entire tool life.

In the nature of things, the titanium-zirconium-molybdenum alloy (TZM) has great dimensional stability and is extremely wear-resistant, meeting the requirements of the plastics industry for the two crucial parameters of thermal conductivity and corrosion resistance. Because of this, the nozzles of hot runner systems at home and abroad are basically processed by TZM rods.

The TZM molybdenum nozzle can reduce the size to the minimum and help improve the space efficiency of the compact hot runner system; the runner is small and smooth, which saves materials while realizing a reliable injection molding process and ensuring high-quality products; the nozzle is manufactured from highly conductive material that transfer precise heat to the gate area for minimal gate vestige and excellent gate marks.

Chinatungsten Online has commanded the entire process chain of molybdenum rods from raw materials to finished products. With more than 20 years of professional production experience, we can provide you with the most favorable and high-quality products to help you maintain your industry competitiveness.

Molybdenum Disulfide, as an Additive, Improves Properties of Nylon Plastic

 Nylon plastic is in the family of synthetic polymer and can replace bronze, brass, steel and aluminum as wear-resistant parts of equipment. It has good toughness, strong wear resistance, oil resistance, shock resistance, tensile and bending strength and good dimensional stability, which is mostly used in fibre cable, films, flooring, rubber reinforcement and shapes like car parts and electrical equipment.

Molybdenum disulfide (MoS2) is used as solid lubricant and plays a very important role in industrial applications. It has a very low friction coefficient (0.03-0.06), high yield strength (3.45MPa), can be used under high temperature (350℃), various ultra-low temperature conditions, or even worked normally at 1200℃ under vacuum conditions, especially has a very good lubrication effect in high-speed mechanical parts. 

MoS2 is added as an additive to nylon materials to improve sliding and friction properties and increase the tensile strength and wear resistance of this material that is still the best choice for many bearing and wear applications.

Nylon 66+MOS2(ash black): with the addition of molybdenum disulfide, nylon 66 provides higher rigidity, hardness and dimensional stability and improves the material bearing and wear resistance as a result of the additive's structure, and its nucleating effect.  

PA6+MOS2 (ash black): adding molybdenum disulfide powder can improve the bearing capacity and wear resistance of unmodified cast nylon without affecting the erosion and fatigue resistance. It is very widely used in manufacturing gears, bearings, star wheels and sleeves.

The properties of nylon plastic nylon include good sunlight resistance power, high melting point, good colour fastness nature, high resistance against insect, bacteria, fungi, rot and other chemicals, compact modular structure, high stretching power and so on. 

The MoS2 provided by Chinatungsten Online features uniform and concentrated distribution of particle size, better dispersibility to make it can better display product characteristics in plastic products. Our regular particle sizes are super fine, technical fine, technical grade and large particle.
