PTFE Sheet, Rod & Tube (Polytetrafluoroethylene, Teflon®)
The original PTFE resin, called Teflon®, was invented by DuPont in 1938. PTFE is a crystalline polymer with a melting point of about 621° F (327° C). Density is 2.13 to 2.19 gm/cc. PTFE has exceptional resistance to chemicals and is stable across wide temperature and frequency ranges.
PTFE has useful mechanical properties from cryogenic temperatures at 500° F (280° C) continuous service temperatures. Its coefficient of friction is lower than almost any other material. It also has a high oxygen level.
PTFE Glass and Carbon/Graphite Filled
PTFE’s mechanical properties can be enhanced by adding fillers such as glass fibers, carbon, graphite, molybdenum disulphide, and bronze. Filled PTFE's maintain their chemical resistance and high temperature characteristics, while glass and carbon/graphite fillers improve stability, mechanical strength and wear resistance.
