Fluoropolymer

PTFE (Teflon)

PTFE (polytetrafluoroethylene), widely known by the Teflon brand name, has one of the lowest coefficients of friction of any solid and is resistant to almost all chemicals. It is used for seals, gaskets, insulators, and low-friction parts. Request a quote or browse all materials.

Typical values for virgin PTFE; filled grades (glass, carbon, bronze) improve creep and wear. These are typical reference values from standard published data, not guaranteed minimums. Request material certificates in your RFQ if properties must be verified.

Advantages

Why engineers choose PTFE (Teflon)

Chemical resistance

Inert to nearly all industrial chemicals.

Low friction

Extremely low friction and non-stick.

Temperature range

Wide service temperature range.

Electrical

Excellent dielectric properties.

Design considerations: Soft and prone to creep (cold flow); high thermal expansion makes tight tolerances difficult; cannot be melt processed by conventional molding.
