Medical grade FEP heat shrink tubing in multi-layer catheters such as fusion spliced PU, PEBAX, and PA

The full name of FEP is Fluorinated ethylene replica, which is the best choice for various types of conduit welding due to the inherent temperature resistance, smoothness, and low shrinkage temperature of the material. The general guide tube is usually composed of a three-layer structure, namely the inner layer is PTFE (Teflon) inner layer, the […]


The cutting-edge technique for creating tight and safe ncapsulation for a variety of components is made possible by Aokeray FEP heat shrink tubing. We offer FEP heat shrinK materials in their expanded form. After a simply heat application, they quickly mold firmly over complicated and uneven shapes to create a robust, totally sealed covering. FEP […]

How working pressure vs burst pressure for polyimide tubing ?

Custom extruders running high stretch ratios during the manufacture of polymeric medical microtubes can also result in significant orientation and residual stress/strain in the finished polyimide tubing . This orientation can significantly increase tensile strength and reduce tube elongation in the machine direction. It also reduces tube working pressure vs burst pressuredue to loss of […]
