Polyamide resin, English name is polyamide, short for PA. Commonly known as Nylon, it is a general term for polymers containing amide groups in the backbone repeat unit of macromolecules. Among the five engineering plastics, it has the largest output, the largest variety and the widest use. The main varieties of nylon are nylon 6 and nylon 66, which occupy an absolutely dominant position. Nylon 6 is polycaprolactam, while nylon 66 is polyhexanediamine adipate, nylon 66 is L2 % harder than nylon 6; Followed by nylon 11, nylon 12, nylon 610, nylon 612, in addition to nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13
