product Information
Nylon
Product Name:Thermoplastic Polyamide Elastomer
TPA1012、 TPA610 and etc.
Product Situation:Guangyin’s TPA is a copolymer with polyamide as the hard segment and polyether or polyester as the soft segment. The hard segment acts as a physical cross-linking point to provide material rigidity, and the soft segment provides material flexibility. The structure gives the material excellent elasticity. Due to its unique chemical structure, thermoplastic polyamide elastomers have the most eclectic properties of thermoplastic elastomers.
