Non-asbestos gaskets are made from high-quality non-asbestos sealing sheets, such as compressed fiber sheets, rubber sheets, or composite materials. Typical compositions include aramid fibers, inorganic fibers, and nitrile rubber binders. These materials offer excellent sealing capability under demanding temperature and pressure conditions.
Compared with traditional asbestos gaskets, non-asbestos gaskets provide safer handling, stable performance, and wide application compatibility.
