GYLON® gasket materials are a family of PTFE based materials incorporating a range of different fillers. These fillers help to increase tensile strength and decrease creep relaxation, a problem which is prevalent in pure PTFE sealing materials. The PTFE base of GYLON® gasket materials helps to provide excellent resistance to chemicals and is designed to offer sealing solutions for various industrial applications. They are often applied in food processing and pharmaceutical applications as they conform to US Food and Drug Administration (FDA) approvals.
