Rubber cork gasket sheets

It is a material made by combining natural cork and rubber, compressed into sheets designed for cutting gaskets.

Why are these two materials combined? Cork offers high compressibility and elasticity, allowing it to adapt well to surfaces while effectively damping vibrations and noise. It is also an excellent insulator. Rubber, on the other hand, is responsible for tight sealing and strong chemical resistance. In addition, it provides mechanical strength and dimensional stability, ensuring that the gasket maintains its properties over time.

Thanks to the combination of cork and rubber, gaskets made from rubber cork:

• conform well to surfaces and reduce the risk of leaks,
• do not crumble during cutting and installation (making it easier to cut precise gaskets),
• return to their original shape after compression (the material doesn’t “settle” over time),
• maintain reliable sealing.

This is why rubber cork is widely used in mechanical engineering, technical installations and various branches of industry. Rubber cork sheets are available in different thicknesses – most commonly from a few millimetres up to around 10 mm.

Rubber cork is used across many industries, including:

• Automotive – engine gaskets.
• Construction – protecting foundations and machinery from vibrations.
• Gas industry – sealing components in valves and fittings.
• Wood industry – production of sound-damping plywood.
• Footwear – orthopaedic insoles.
• Electronics and electrical engineering – spacing components in the power industry, as well as gaskets and vibration isolation for transformers.
