PTFE is a completely fluorinated polymer that is the most chemically resistant polymer available. PTFE can withstand a very wide temperature range from -300ºF to +500ºF. It is inert to most chemicals and solvents with very few substances that degrade the material (notably fluorine, chlorine trifluoride, and molten alkali metal solutions). PTFE is also very slippery and repels virtually everything making it perfect for applications that require a high coefficient of friction. PTFE is not crossed-linked like a regular elastomer and therefore has poor elastic memory, can deform under constant compressive load and can be damaged during installation.


PTFE is recommended for:
Excellent resistance to almost all chemicals
Not subject to aging, so a near infinite shelf / storage life
Can be use in food, chemical and medical industries
Low elasticity (memory)
Low coefficient of friction
