PTFE 'O' Rings
Polytetrafluoroethylene (PTFE) is a high molecular weight polymer, one of the most
versatile plastic materials known and useful for a large range of products for
applications excluded from other materials. Teflon o-rings are known for high heat
resistance, high resistance to chemical agents and solvents, anti-adhesiveness,
dielectric properties, low friction coefficient, and non-toxicity.
The tensile and compressive properties are to a large degree influenced by the
working processes and the polymer used. PTFE, however, can be used continuously
at temperatures up to 250°C (482°F), while possessing still certain compressive
plasticity at temperatures near to the absolute zero.
