Pebax (polyether block polyamide) is a thermoplastic elastomer, composed of rigid polyamide segments and flexible polyether segments. It combines the strength of plastics with the elasticity of rubber. Its advantages are as follows: 

Excellent biocompatibility; 

Super flexibility and elastic memory; 

Chemical resistance and anti-static property; 

Ultra-thin wall design 

Self-lubricating surface 

The maximum heat shrink ratio can reach 1:2.
