Polyester Tubing for Medical Applications

Duke Extrusion extrudes polyester tubing, commonly referred to as PET tubing, or polyethylene terephthalate. PET is a very lightweight thermoplastic polymer resin that offers excellent dielectric strength and wear resistance. Polyester tubing is UV resistant and exhibits very low water absorption. Polyester tubing also offers outstanding optical clarity for image and light transmission applications such as optical coherence tomography (OCT) catheters.

PET is a semi-crystalline thermoplastic polyester with a high flexural modulus; it can also hold extremely thin wall thicknesses. Polyester extrusion is compatible with EtO and radiation sterilization and is readily bondable with adhesives as well as thermal bonding.  PET tubing can be formed into specific geometries, and DUKE Extrusion offers flares and tipping as secondary operations.

Polyester Reinforcement for Other Tubing

In addition to PET tubing, DUKE Extrusion processes PET monofilament and multifilament into the walls of a large variety of thermoplastics, such as Pebax®, polyurethanes, and others. PET filaments are braided, coiled, or positioned axially to the tubing wall to provide increased strength, kink resistance, and torque transmission, and to reduce axial elongation. DUKE Extrusion offers design recommendations to achieve your product’s performance requirements.
