The title kinda explains itself tbh. I'd like a PEBA addition to the PolyFlex lineup. It's by far the most underrated flexible material in the 3dp world. Low density, incredible layer adhesion, and the highest energy return of any flexible polymer. It's used in the midsoles of high end running shoes and football helmets for shock absorption.

Out of curiosity can I ask what the use case is?
Cuz I’m having trouble thinking of some where PEBA is necessarily the right choice, rather than any other TPE

.... I play a hobby level of Nerf, and use "plunger pads" on the plunger heads. So when the parts slam into each other, they don't snap and break each other.

Interesting…. And standard TPE isn’t sufficient?

The key with PEBA is the rebound. It's nothing like any kind of TPU/TPE/TPC

I’ll have to look into that a bit more 👀
