Polyamide
Polyamide:
(PA) is a thermoplastic resin containing repeating amide groups on the main chain of the molecule. It is commonly known as Nylon or nylon. It is the first synthetic fiber appearing in the world and has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubrication, low coefficient of friction, certain flame retardancy, and a density of 1.15 g/cm³. It is a resin developed by DuPont Company in the United States for fiber. Industrialization was achieved in 1939. Polyamides include aliphatic PA, aliphatic aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large yields, and wide applications. Its naming depends on the specific number of carbon atoms of the synthesized monomer. Polyamide is called nylon when used as a plastic, and nylon when used as a synthetic fiber. It can be made into long or staple fibers and is relatively wear-resistant during wearing.
