PTFE is principally used as a gasket material because of its capability to remain unaffected by the majority of chemicals used in industry. In most cases, it is also classified as a food grade material, making it acceptable to both medical and food production industries. There are more types of PTFE gasket materials; among others is Virgin PTFE, modified PTFE and filled PTFE.
