-Superior chemical resistance
-Very low coefficient of friction
-Longest aging life in plastics
-Good dielectric properties
-Non-toxic
-Non-stuck
Applications
•Bearings
•Gaskets
•Sealing rings
•Wear rings
•Friction pads
•Insulators
•Chemical resistance linings
•Medical apparatus such as hoppers, beakers
