PTFE key features

Main PTFE product characteristics

Polytetrafluoroethylene (PTFE) is a unique material offering a combination of the following characteristics


extremely low surface energy thus providing excellent anti-stick, non-wetting contact surfaces.

Atmospheric Ageing

are transparent to UV light and extremely resistant to oxidation, surface fouling, discolouration and embrittlement.


are resistant to enzymatic and microbiological attack, and do not contain any additives which could provide a substrate for fungal or bacterial growth.


depending on types used service temperatures can go up to 240°C.


remain stable and completely functional down to cryogenic temperatures.


are chemically inert and pure and have no effect on process fluids.


resist the most aggressive organic and inorganic chemicals & solvents.


are extremely hydrophobic and completely resistant to hydrolysis.


are extremely hydrophobic and completely resistant to hydrolysis.


have excellent fatigue resistance in Stress applications involving flexing or vibration.

Long Service

excellent resistance to ageing at high temperatures and in the presence of oils, solvents, oxidising agents among others. As no leachable or degradable stabilizing agents are involved this is a big safety factor when designing for long life.
