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.
