For nylon 6, the monomer has six carbon atoms, hence the name nylon 6. The chemical formula of nylon is (C6H11NO)n. Nylon 6, which is also referred to as polycaprolactam, is a type of semicrystalline polyamide polymer. Unlike the majority of other nylon variants, nylon6 is not produced through condensation polymerization; instead, it undergoes ring-opening polymerization. This distinctive property distinguishes it from both condensation and addition polymers.
Nylon 6 is only available in natural color (white) and black from the factory. Manufacturers can add color masterbatch to natural nylon 6 according to their actual needs for color matching.
Common applications of nylon 6：
Automotive: Under-the-hood components, gears, bearings.
Consumer Goods: Sports equipment, combs, toothbrush bristles.
Electrical Components: Cable ties, connectors, housing.
Textiles: Used to produce nylon fibres for clothing.
Industrial: Gears, rollers, and machine parts.
