Nylon sheet macromolecular main chain of the polyamide resin is a repeating unit of the polymer containing amide groups in general. Engineering plastics for the production of the five largest and most varied, the most widely used species. The main varieties of nylon is nylon 6 plate and nylon 66 block, were overwhelmingly dominant, nylon 6 sheets polymerization of caprolactam and nylon 6 sheets is poly adipic acid has diamine nylon 66 than nylon 6 to 12% of hard; nylon reform vast amount of varieties, such as reinforced nylon plates, conductive nylon sheet, nylon board and other polymer blends and alloys, etc., to meet the special requirements of different, widely used as metal, wood and other traditional materials
