Nylon is the generic name for all long-chain fiber-forming polyamides with recurring amide groups. Polyamides (nylon) comprise the largest family of engineered plastics with a very wide range of applications. Polyamides (nylons) are often formed into fibers and are used for monofilaments and yarns. Characteristically, polyamides (nylons) have low-friction properties, are very resistant to wear and abrasion, have good mechanical properties even at elevated temperatures, have low permeability to gases, and have good chemical resistance. When applied to metal substrates, a nylon powder coating can be an economical alternative to more expensive Fluoropolymer resins where low friction and abrasion resistance at low temperatures are the primary performance characteristics.
