Compressed non-asbestos gasket materials can be made of non-asbestos fibers such as carbon fiber, aramid fiber, cellulose or in-organic fibers like fiberglass. They are combined with specific rubber compounds and clay fillers to produce a material with excellent temperature and pressure performance when used as gasket. Combining inorganic and organic fibers with rubber allows for a range of variants that have different mechanical properties. These compressed non-asbestos gaskets provide the user with high performance sealing, torque retention, chemical compatibility and heat resistance. Gaskets cut from compressed non-asbestos materials are designed to perform in applications involving, air, water, steam, oils, acids and general chemicals.
