|
PTFE has become the
material choice when looking for a unique combination of properties to provide
performance unmatched by any other polymer. PTFE and PTFE with selected fillers
offer the following exceptional characteristics: |
|
- excellent chemical
resistance
- very wide service
temperature range from -260°C to +260°C
- unsurpassed dielectric
properties
- high purity and
inertness
- the lowest coefficient of
friction of any solid
- a broad range of
mechanical properties

PTFE was
discovered in 1938 by Dr Roy Plunkett of DuPont and was later made commercially
available under the well known trade name of Teflon®. Since then other
manufacturers have introduced grades of PTFE and there are now 5 major
established suppliers of PTFE in its raw form:

In recent
years manufacturers in Russia and the Far East have also started production of
raw polymers.
The properties
of raw (virgin) PTFE can be enhanced by blending it with a range of materials
known as fillers to make PTFE Compounds. There is an extensive range of PTFE
Compound products (over 300) on the market.
