Cast nylon plate
Also known as MC nylon: English name? Monomer? Casting? Nylon? It is called monomer casting nylon in Chinese. "Replacing steel with plastic, excellent performance" is widely used.

Compared with ordinary nylon, the friction coefficient is lower (it can be reduced by 50%) and the wear resistance is improved (it can be increased by 10? Time). ? 4:PA6+？ Molybdenum disulfide (grayish black): Molybdenum disulfide powder can improve the bearing capacity and wear resistance of unmodified cast nylon without affecting its impact resistance and fatigue resistance. Widely used in manufacturing gears, bearings, star wheels and shaft sleeves. ? 5:PA6+？ Solid lubricant (gray): The patented formula of cast nylon 6 is adopted, which contains solid lubricant. This material has self-lubrication, excellent friction, outstanding wear resistance and pressing speed (5 times higher than ordinary cast nylon). It is especially suitable for moving parts that run at high speed and cannot be lubricated, and it is a perfect supplement to oil-containing nylon.

Open classification:?
Nylon 6, plastic board, nylon 66, nylon board, nylon board?
Nylon is a kind of polymer material, and its most excellent characteristics are wear resistance and strong water absorption.
MC nylon is both MCPA cast nylon and cast nylon. It is similar to the process of copper-iron casting, and the raw materials can be directly injected into the preheated mold for rapid polymerization and curing to make MCPA cast nylon. It is a new type of engineering plastic, and it is a polymer engineering plastic with high strength, good rigidity, low density, wear resistance, friction reduction, oil resistance, corrosion resistance, easy processing and molding, and moderate price. "Plastic replaces steel and has excellent performance" because of its excellent comprehensive performance.
Properties of 1.MC nylon;
(1)MCPA cast nylon is a high crystallinity polymer with a molecular weight as high as 10000- 130000, while the molecular weight of ordinary nylon 6 is only about 20000. So it has high strength and can bear the load for a long time.
(2) The density is low, and its value is1.1.15, which is only 1/7 for steel,18 for copper and18 for alloy aluminum. Because of its light weight, making mechanical parts can reduce power and inertia, and it is also convenient for loading, unloading and maintenance.
(3) It has good resilience, and the curved surface of the product will not be permanently deformed, thus maintaining toughness to resist fracture caused by repeated impact loads. This is a particularly excellent material for parts bearing high impact load. Especially, it has good creep resistance and can bear the heavy load of the bearing for a long time.
(4) Friction resistance and high wear resistance are its unique excellent characteristics, and wear resistance and self-lubrication provide better working performance than bronze cast iron, carbon steel and phenolic laminate in oil-free (or deoiling) lubrication applications, reducing consumption and saving energy; Generally speaking, it has special self-lubricating performance at medium and low speeds, and can still work normally without lubrication. Different from metal, the wear increases proportionally with the increase of service time, while nylon wears slightly at first and rarely afterwards. Because of its low friction coefficient and lower hardness than metal, MC nylon does not damage the worn parts; This is very beneficial to the manufacture of rollers, bearings, wheels, pulleys, gears and turbines.
(5) The modulus is much smaller than that of metal materials, and the attenuation rate of vibration is dozens of times larger than that of steel. It has special vibration absorption and noise reduction function, and is the best material to reduce mechanical noise when used as gears, wheels and pulleys. Compared with steel and copper gears, nylon gears can reduce noise by 20-25 dB, which provides a better practical method to prevent noise than metal gears. ?
(6) Low friction coefficient, which makes it possible for it to be widely used in friction parts;
(7) High chemical stability, resistance to alkali, alcohol, ether, hydrocarbon, weak acid, lubricating oil, detergent and water (seawater), odorless, nontoxic, tasteless and rustless, which provides excellent conditions for its wide application in alkali corrosion resistance, environmental protection and sanitation, food, textile printing and dyeing, etc.
(8) Simplify machine maintenance, save labor, have excellent mechanical cutting performance and improve labor productivity.
(9)MC nylon is limited to the following environments and media:
A. The service temperature exceeds120℃ for a long time; ?
B, strong acid, phenol, sodium chlorate, barium chloride, etc. ; ?
C, key parts of high-precision machines.
(10) casting process is easy to form. Ordinary plastics and nylon can only be formed by extrusion, casting and pressing. And the product size is often limited. Products weighing more than 2 kilograms are difficult to form, while the size of MCPA cast nylon products is not limited, and products can be produced from several kilograms to hundreds of kilograms. ? Polyamide is usually called nylon.
