PTFE Sheet

PTFE has excellent chemical resistance and the lowest co-efficient of friction of any solid plastic. This material is tough and flexible, has a non-stick surface and can be used at temperatures between -260°C and +260°C. PTFE is impervious to water, has very good electrical insulation properties and is non-flammable. Applications include; valve seats, gaskets, 'O' rings, back-up rings, linings, insulators and bushes.
