PTFE and FEP are part of a family of fluoroplastics materials.
These materials are characterised by their almost total chemical
and solvent resistance. They have a working temperature range
of -200°C to +260°C. They have a very low coefficient of friction,
and remain flexible at cryogenic temperatures.
Electrical resistance is very high, and their dialectric properties
make them a popular choice for electrical insulators.

These materials are naturally non-flammable
and also non-toxic. There is total resistance to UV radiation.
Due to their low co-efficient of friction, it is very difficult to use
adhesives on these materials. They resist welding, unless performed
at high pressure and temperature.
PTFE and FEP can be sterilised by Autoclaving, Gamma Irradiation,
Ethylene Oxide or Dry Heat.
