Polyimide Tubing

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.

Typical Applications

  • Cardiovascular catheters
  • Urological retrieval devices
  • Neurovascular applications
  • Fiber optics
  • Intravascular drug delivery
  • Balloon angioplasty & stent delivery systems
