PA1012
PA1012 (Polyamide 1012) is a long-chain bio-based polyamide produced by polycondensation of decamethylenediamine and dodecanedioic acid, combining the advantages of PA10 and PA12 series. PA1012 features very low water absorption, excellent chemical resistance, and good flexibility, serving as a cost-effective alternative to PA12 and PA11.
