Quick Detail:
ERM sealing company is specilized in virgin PTFE gasket and filled PTFE gakset .
Description:
Virgin grade PTFE (Teflon®) gaskets are made from 100% pure material which is used in most general applications. It is extremely soft and formable and is often used for chemical resistant seals and gaskets. It is made directly from the resin producer and has never been processed into a shape. It possesses the highest physical and electrical insulation properties and has increased resistance to creep (compression) under load. Virgin grade PTFE can be recognized by its whiter color compared to mechanical grade PTFE.
Filled PTFE (Teflon®) gaskets are made from PTFE which integrates additives and fillers in order to improve the performance of the gasket. This improves the gaskets ability to wear and enhances its unique combination of chemical, physical and electrical properties. Filled Teflon® is the most common type of PTFE gasket for industrial use as it exhibits improved mechanical strength compared to Virgin PTFE. Glass, carbon and fiber particles are typical fillers that are used to enhance the mechanical strength of the gasket depending on the application.

Competitive Advantage:
Low friction and minimum power consumption are the decisive advantages offered by PTFE
Gasket.
These seals can be used without problems also with dry operation or insufficient
lubrication. The materials thermal properties, with an operating range of -130°C to +200°C,
are unrivalled. Moreover, PTFE is featured by high chemical resistance and a low breakaway
torque after standstill.
