Non-asbestos gaskets come in a variety of basic materials comprised of carbon, graphite, fiberglass, aramid fiber, Kevlar and other mineral fibers. The basic components of the non-asbestos materials used in gasket construction are elastomer and filler.Add special adhesives and a little packing into it, then roll and sulfurated. The elastomer composition corresponds to the application of the gasket, assisting in the categorization and selection of the gasket best used for the service it will be performing. It is a replacement of asbestos gasket.
Non-asbestos Gasket has better strength, elasticity.It has supper strong anti-penetrate performance. Non-asbestos Gasket is a better choice than asbestos gasket in high temperature and high pressure condition. And Non-asbestos Gasket is product using material with environment protection.
Typical Properties of Common Elastomers (Rubber Compounds)
NBR - good for oils, gas, mild chemicals and water
SBR - good for saturated Steam, mild chemicals inert gas and water
Neoprene - good for saturated steam, refrigerants, oils, fuels, mild acids and alkalies and water.
EPDM - good for saturated steam, mild chemicals and water
