PTFE is one of the most chemically inert materials known and is used in many different applications and industries.
PTFE is an incredibly versatile material with a wide variety of applications. It has extreme chemical resistance, a massive temperature range, is completely unaffected by UV, excellent electrical insulation properties. Flexible, low friction, inert.
Extreme chemical resistance
Very low coefficient of friction
Wide temperature range
Excellent thermal stability
Excellent electrical insulation
Almost infinite shelf life
Virgin PTFE (unfilled) is most often used where mechanical properties are not the most important requirement.
Our most recent projects where Virgin PTFE has been specified include high voltage electrical connectors, environmental seals within commercial fishing reels and another where virgin PTFE was specified as a diaphragm material, bonded to an elastomer substrate to offer the best of chemical resistance and purity on one side combined with flexural properties of the elastomer.
Other applications include:
Pump housings, valve seats, gaskets, roller coverings, shaft bearings, filter housings, etching plates, shaft seals, slide runners, chemical engineering, machine parts, transport and conveyor technology, pump and instrument construction, electrical industry, electronics, laser technology, fume purification, pure water production, cryogenics, filter technology, food and medical technology.
