Composite Tubing

Thin-wall polyimide tubing can be blended, braided, or layered with multiple polymers to get the performance characteristics your application requires:

  • Low-friction layer inside or outside
  • Fusible thermoplastic outer layer
  • Improved kink radius
  • Excellent torque when braided

Our composite tubing features:

  • More than 80 layer combinations
  • Many materials, including PTFE, Nylon, Pebax®, Polyurethane, Polyphenylsulfone, and Polyimide

Braid-Reinforced Tubing

Our braid-reinforced tubing comprises 4+ layers with wire braid in the middle for torque, tensile strength, and kink resistance. Why choose polyimide over extrusions?

  • Smaller diameters
  • Thinner wall thickness
  • Tighter tolerances
