Polytetrafluoroethylene (PTFE)

A fluorocarbon solid made from carbon and fluorine, PTFE is hydrophobic, and has one of the lowest coefficients of friction of any solid. Commonly referred to by its brand name, Teflon®, PTFE is most commercially known for its role as an effective non-stick cookware coating. Its non-reactive properties make it ideal for use in environments where aggressive chemicals are present. A thermoplastic with a high melting point (as compared to other plastics and elastomers), PTFE can withstand tough, high-temperature conditions.
