Pellethane® is a family of medical-grade thermoplastic polyurethane elastomers. It has superior resilience, low temperature properties and exceptionally smooth surfaces.

Thermoplastic elastomers (TPE) have the processing abilities of thermoplastics and performance like thermosett rubber, but they have greater biocompatibility than rubber.
