Composite Tubing
Meeting Your Performance Characteristics Requirements
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
Precision Wire Coatings
For Your Application
Because of its outstanding electrical insulation properties, polyimide makes an ideal wire coating, with:
- High dielectric strength
- Precision tolerances
- Resistance to chemicals and high temperatures
- Thin wall thickness
- High strength
Are You Bonding a Nitinol Component to Polyimide Tubing?
We specialize in complex manual nitinol wire braiding and forming. Manual forming allows for a more customized product, with a wider range of sizes, shapes, and densities than machine or laser cutting and forming.
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
We carry a variety of configurations of braid-reinforced tubing.
- ID range: 0.013"–0.074"
- Wall thickness range: 0.002"–0.008"
Our made-to-order braid-reinforced tubing is manufactured to your specifications:
- ID range: 0.004"–0.420"
- Wall thickness range: 0.0005"–0.010"
