Abestos Free Gasket
Description
Asbestos free gaskets are
made of aramid fiber and artificial rock wool (sepiolite). They are made of
natural rubber, styrene-butadiene or NBR rubber. They are specially made by
roll pressing and have temperature resistance, pressure resistance and oil
resistance. Excellent air tightness and compression resilience; high mechanical
strength materials are easy to cut and form. Wire or metal platinum sheets can
be entrained according to customer requirements. According to the physical performance grade, it can be divided into three different grades of low pressure, medium pressure and high pressure, as well as oil resistant, acid resistant, pressure resistant, high temperature resistant, refrigeration refrigerant plates, airtight plates, marine sealing plates and other special non-asbestos gaskets. On the basis of the above materials, the wire is reinforced, the graphite is coated to increase the temperature resistance, and the graphite-containing non-asbestos graphite plate can be customized according to the special needs of the customer, and other non-asbestos materials and various gaskets can be customized.
Application
Medium: various gases, water, water vapor, chemical solvents and various oils, etc.
Industry equipment: products are widely used in power generation, metallurgy, shipbuilding, petrochemical and other industrial applications. Water, steam, oil and other media sealing pipe flanges, valves, heat exchangers, pressure vessels, mechanical equipment and engines, compressors, internal combustion engines Industrial equipment such as machinery, instrumentation and heating.
Size
According to the customer’s request, and all products with a thickness of 0.8 mm or more can be reinforced with clip wire mesh, can be coated with graphite and double-sided anti-stick treatment.

Note
ASBESTOS FREE GASKET or NON ASBESTOS GASKET generally mentioned in Europe and the United States refers to 100% asbestos-free gaskets. However, in the domestic market, we generally refer to gaskets containing a certain amount of asbestos (5-20%). Non-asbestos gaskets or non-asbestos gaskets, so customers need to specify them when ordering.
