Product Detail

Perfluoroalkoxy PFA Flexible Tubinge FEP Tubing KXT PFA1125

PFA (PerFluoroAlkoxy) tubing offers similar properties to FEP, but is considered more of a premium resin. PFA is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. PFA tubing offers high melt strength, stability at high

processing temperatures, excellent crack and stress resistance, low coefficient of friction, and more than 10 times the Flex life of FEP. It has high resistance to creep and retention of properties after service at 500°F (260°C), with useful properties at -320°F (95°C). PFA tubing

 

Advantages
