Tekni-Plex - Polyamides

Polyamides, also known as nylons, and polyamide copolymers (e.g., Arkema’s Pebax® polymer) are used in a wide range of catheter shafts and outer layers. They are the materials of choice in balloon and stent delivery catheters. The polyamides that dominate this catheter market are soft grades, such as nylon 11 and nylon 12. Polyamide copolymers offer a wide range of durometer and flexibility so that catheters can be designed with variable flexibility along the shafts.
