VESTAMID? E 40-S3
Polyamide 12
Typical Applications: noiseless gears, seals, functional elements of sports shoes, processing aids in the extrusion of thermoplastic polyurethanes, films
PA 12 elastomers, the most important subgroup of polyamide elastomers, belong to the increasingly important material class of thermoplastic elastomers (TPE). Because of their excellent properties, they are indispensable in many applications.
PA 12 elastomers are block copolymers consisting of PA 12 segments and polyether segments. PA 12-rich products have the major properties of PA 12, while the elastomer characteristics become more apparent with increasing polyether content. That is the polymers become more flexible, with higher impact strength at cold temperatures.
