Cork Rubber Sheet

 Cork Rubber Sheet

Make by mixing a bark of a pith tree, synthetic rubber and pitch binder. Mix press in the form of the block, after pasting cut on sheets. The material has properties of elasticity of rubber and compressibility of a pith tree that gives to it excellent characteristics.Can be used as various linings in cars, tractors, the ships, oil pipelines, an electric equipment. It is a high-quality kind of a new sealing material which can be used in conditions of average pressure. Sheets have fine elasticity, good resistibility to water, oil and solvents, and also good compressibility.
