What materials do nylon rope manufacturers use? Commonly known as Polyamide nylon, the English name polyamide (PA) is a thermoplastic resin with repeated amide groups -[NHCO] in its main chain. Include aliphatic PA, aliphatic aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application. Its name is determined by the specific number of carbon atoms in the synthetic monomer.
The main varieties of nylon are nylon 6 and nylon 66, occupying an absolute dominant position, followed by nylon 11, nylon 12, nylon 610 and nylon 612, in addition to new varieties such as nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13, nylon 6I, nylon 9T and special nylon MXD6 (barrier resin). There are many modified varieties of nylon.
Such as reinforced nylon, MC nylon, RIM nylon, aromatic nylon, transparent nylon, high impact (super-tough nylon, electroplated conductive nylon, flame retardant nylon, nylon and other polymer blends and alloys, etc., which meet special requirements and are widely used as a variety of structural materials instead of traditional materials such as metal and wood.
Nylon Z is one of the important engineering plastics, and its output is one of five general engineering plastics.

Properties: Nylon toughness angle translucent or milky white crystalline resin. As an engineering plastic, the average molecular weight of nylon is 1.5-30,000. Nylon has high mechanical strength, high softening point, heat resistance, low friction coefficient, wear resistance, self-lubrication, impact resistance and sound absorption, oil resistance, weak acid resistance, alkali and solvent resistance, good electrical insulation, self-extinguishing, non-toxic, tasteless, good weather resistance and poor dyeing property.
The disadvantage is that the water absorption rate is large, which affects the dimensional stability and electrical properties. Fiber reinforcement can reduce the water absorption rate of the resin, so that it can work under high temperature and high humidity. Nylon has a good affinity with glass fiber.
Nylon 66 has high hardness and rigidity, but poor toughness.
The toughness order of nylon is PA66 < PA66/6 < PA6 < PA610 < PA11 < PA12. The flammability of nylon is UL94V-2, the oxygen index is 24-28, the decomposition temperature of nylon is > 299℃, and it spontaneously ignites at 449~499℃.
Nylon has good melt fluidity, and the wall thickness of the product can be as small as 1mm.
