Asbestos & Non Asbestos Gaskets

Asbestos & Non Asbestos Gaskets

A gasket material that is comprised of asbestos fibers encapsulated within a rubber binder. This type of gasket is tough, durable and dimensionally stable, relatively incompressible and exhibits low creep characteristics. It also has the ability to effectively form a seal over a wide range of service conditions which has given it a good reputation. Compressed asbestos fiber(CAF) gaskets have good chemical resistance capabilities and a good working temperature range of cryogenic to 1,100F. It is less suitable for low bolt loads such as use with non-metallic flanges and low grade bolts, and is not suitable for use in stainless steel flanges due to its chlorine content which will damage the flanges. However, CAF gaskets can be installed relatively easily due to their ability to handle mechanical abuse, incorrect fitting and bolt-load retorquing.

CAF Non Asbestos Gaskets are die cut or circle cut from compressed asbestos fibre, non asbestos jointing which are manufactured from carefully selected chrysolite fibre intimately blended with suitable heat resistant binders etc. and vulcanized into sheets of homogeneous compositions and uniform thickness. CAF Non Asbestos cut gasket Yielding or flow of material into the imperfections of joint contact faces effects seal. In this way gasket provides an unbroken barrier of homogenous structure through which no pathway exist for escape of confined media.
