Sponge Gaskets Dealers in Diamond Harbour Road, Kolkata

We are offering sponge gaskets. Sponge rubber, also called "expanded" or "cellular" rubber, is manufactured by including a gas-forming ingredient (blowing agent) in the rubber formulation. As the rubber vulcanises, it reaches a temperature at which the blowing agent decomposes and gas bubbles form, creating individual cell structures in the rubber. This is followed by a curing until vulcanization is complete. The vulcanization process preserves the cell structure formed by the gas in the interior of the component. This makes the final gasket softer, easier to compress and lighter in weight. Hence sponge gaskets require much lesser force to compress as compared to solid rubber gaskets.
