Polyimide(PI) Tubing with torque transmission and column strength

Polyimide is a polymer thermoset plastic that has exceptional thermal stability, chemical resistance, and tensile strength. These characteristics make polyimide an ideal material for high-performance medical applications. The tubing is lightweight, flexible, and resistant to heat and chemical interaction. It is widely used in medical devices such as cardiovascular catheters, urological retrieval devices, neurovascular applications, balloon angioplasty & stent delivery systems, intravascular drug delivery, etc. AccuPath®‘s unique process also allows tubing with thinner walls and smaller outer diameters (OD) (walls as low as 0.0006 inches and OD as low as 0.086 inches) to be manufactured with greater dimensional stability than tubing manufactured by extrusion. In addition, AccuPath®‘s Polyimide (PI) tubing, PI/PTFE composite tubing, black PI tubing, black PI tubing, and braid-reinforced PI tubing can be customized according to drawings to meet different requirements.
