PTFE Stick

Using a wide range of temperature (from-180 degree +250 degree Celsius). With corrosion-resistant to all chemicals except fluoride and alkaline metal. Excellent mechanical properties include resistance to aging especially for bends and swing application. Outstanding flame retardant (meets ASTM-D635 and D470 test steps in the air regulations for fire-retardant materials. 

Excellent insulation properties (regardless of how the frequency and temperature) Extremely low water absorption rate, and have self-lubricating and non adhesive and a series of unique properties. Disadvantages: high expansion rate, low mechanical strength, wear and not creep but added bronze powder can increase the wear resistance of high strength.
