VESTAMID® Care PEBA

Flexible Multi-Layer Catheter Tubing through co-extruding and reflowing bondable VESTAMID® Care PEBA directly to Daikin Neoflon® EFEP in one step process without the need for adhesives and surface treatments.

Evonik and Daikin have created a complementary product technology for the medical device market in angioplasty and guidewire catheter application: A PEBA-Fluoropolymer Multi-Layer Catheter Tubing in One-Step Coextrusion.
