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.
