PTFE Liners

• MicroLumen’s unique process of incorporating fluoropolymers with Polyimide provides mechanical properties far superior to conventionally extruded medical tubing. 

• PTFE/FEP composites offer the benefits of fluoropolymers without the bonding and flaking problems typically associated with Pure PTFE liners.

• Both PTFE/FEP composites and ultra-thin Pure PTFE liners reduce the coefficient of friction.

• Coefficient of friction:
   Pure PTFE = 0.1
   PTFE composite = 0.3
   Polyimide = 0.5

• Reduced coefficient of friction is ideal for guide wire use

• PTFE/FEP Composites can withstand gamma sterilization, whereas Pure PTFE liners can not.

• Etched Pure PTFE constructions available.
