PA612
PA612 (Polyamide 612) is a long-chain semi-crystalline polyamide produced by polycondensation of hexamethylenediamine and dodecanedioic acid. It features very low water absorption and outstanding dimensional stability. PA612 combines good mechanical properties, chemical resistance, and electrical insulation, widely used in precision mechanical parts and wire & cable applications.
