Non Asbestos Gaskets  

Non Asbestos GasketsA gasket is a compressible material, or a combination of materials, which when clamped between two stationary members prevents the passage of the fluid across these members. To prevent passage of fluid, the gasket must be able to flow into (and fill) any irregularities in the mating surfaces being sealed, while at the same time be sufficiently resilient to resist extrusion and creep under operating conditions. The seal is effected by the action of force upon the gasket surface (usually by bolts), which compresses the gasket, causing it to flow into any surface imperfections

 

Gasket Materials
Wide varieties of materials are used in the manufacture of gaskets. This section is aimed at providing a brief overview of the common materials. For simplicity they are divided into 4 parts.
• Elastomeric materials
• Fibrous materials
• Other materials
• Metallic materials

 

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