PTFE - is an acronym for polytetrafluoroethylene, which is a registered trademark of DuPont. It is utilized as a sealing material because it is able to withstand significantly more aggressive chemical environments, (including highly oxidizing environments), than both rubber or graphite based material. However its operating temperature, pressure and mechanical performance can be inferior to standard non-asbestos or graphite gasket materials.
PTFE is principally used as a gasket material because it is essentially inert and has the capability to remain unaffected by the majority of chemicals used in industry. Also, it can be classified, in most cases, as a food grade material, making it acceptable to both medical and food production industries. There are four basic types of PTFE gasket materials. Virgin PTFE , filled PTFE, restructured PTFE and expanded PTFE
