PTFE key features

Main PTFE product characteristics

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

Adhesion

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.

Bio-Degradation

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

Heat

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

Cold

remain stable and completely functional down to cryogenic temperatures.

Contamination

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

Corrosion

resist the most aggressive organic and inorganic chemicals & solvents.

Humidity

are extremely hydrophobic and completely resistant to hydrolysis.

Friction

are extremely hydrophobic and completely resistant to hydrolysis.

Mechanical

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.
