Polyimide Tubing
Thermoset polyimide tubing and coated wire is a highly versatile product, with a wide range of uses in high performance medical devices. Typical medical applications include cardiovascular catheters, retrieval devices, push rings, marker bands, angioplasty, stent delivery devices, neurological devices, electrical insulator applications, and drug delivery systems.
Polyimide thermoset plastic provides excellent mechanical, thermal, electrical, and chemical resistant properties. Polyimide brings the following benefits to medical tubing: flexibility, high tensile strength, biocompatibility, low friction, transparency, tight tolerances, thin walls, smooth surface, pushability, and column strength. Polyimide is USP Class VI compliant and meets ISO 10993 biocompatibility requirements for a class III device. Polyimide maybe sterilized via gamma, EtO, & E-beam sterilization methods.
