What is Nylon 6?
Nylon 6 is a synthetic polyamide produced by ring-opening polymerisation of ε-caprolactam. Unlike Nylon 6,6 which is made from two monomers, Nylon 6 is produced from a single monomer. It has excellent mechanical properties, good chemical resistance, and self-lubricating properties. The repeating unit –NH(CH₂)₅CO– gives it a regular structure with strong intermolecular hydrogen bonding between amide groups.
