Explanation
Also known as nylon 12. Dodecalactam was ring opening polymerization catalyzed by 1% p-benzenesulfonic acid at 3O0 ° C to crystallize thermoplastic resin. It is a resin with low melting point, low water absorption, high crystallinity, easy processing and molding, good low temperature resistance, and wide use temperature range (55-90 ° C).
