Polyamide is commonly known as Nylon (Nylon), called Polyamide (PA for short), has a density of 1.15g/cm, is a general name for thermoplastic resins containing a repeating amide group- [ NHCO ] -in the main molecular chain, and comprises aliphatic PA, aliphatic-aromatic PA and aromatic PA. The aliphatic PA has many varieties, large yield and wide application, and the name is determined by the specific carbon atom number of the synthetic monomer. Invented by the american famous chemist caroth and his research group. Nylon is a term for polyamide fiber (nylon) and can be made into long fibers or short fibers. Nylon is a trade name for polyamide fiber, also known as Nylon (Nylon). The English name of Polyamine (PA) is the basic component of aliphatic Polyamide which is connected by amido bond- [ NHCO-.

The nylon rod has the characteristics of good toughness, strong wear resistance, oil resistance, shock resistance, tensile strength, good bending strength, small water absorption, good dimensional stability and the like, so that the nylon rod is used for processing various wear-resistant high-strength parts.
