The TPE family has adhesion on any type of polyamide tested in the study, including undried materials, making them truly Universal polyamide overmold TPEs. Novel developments in thermoplastic elastomers have been driven by application demands that far exceed the TPE chemistry material selection Page 1 of 11 space illustrated in this figure. The current paper offers a novel robust TPE material selection for overmolding on to Polyamide.
