PI tubing for catheter

Polyimide (PI) is an organic polymer material with excellent comprehensive properties. It has high temperature resistance of more than 400 ℃, long-term use temperature range - 200-300 ℃, no obvious melting point, high insulation performance, dielectric constant of 4.0 at 103 Hz, dielectric loss of 0.004-0.007, belonging to class F to H insulation material.
Polyimide sleeve is spiral wound with multi-layer polyimide film and bonded with special glue. The bushing made of this material has good electrical, physical and mechanical insulation properties. At very high and very low temperature, the casing has remarkable radiation resistance and flexibility.
