Rubber cork gasket sheets

Rubber-cork is a composite material created by blending natural cork with rubber. The mixture is compressed into sheets that can be easily cut into gaskets and sealing elements.

The reason for combining these materials lies in their complementary properties. Cork offers excellent elasticity and compressibility, allowing the material to conform easily to different surfaces while also helping absorb vibrations and reduce noise. It also acts as an effective thermal and acoustic insulator. Rubber, on the other hand, provides strong sealing performance and resistance to various chemicals. In addition, it improves mechanical durability and dimensional stability, helping gaskets maintain consistent performance over time.

By combining cork and rubber, this material offers several advantages when used for gasket production:

• it conforms well to uneven surfaces, helping prevent leaks,
• the material remains stable during cutting and installation and does not crumble,
• after compression it returns to its original shape,
• it maintains a dependable seal over time.

Because of these qualities, rubber-cork sheets are widely used in mechanical engineering, technical installations, and many industrial applications. They are available in a range of thicknesses—typically from a few millimeters up to around 10 mm.

Rubber-cork materials are used across a wide range of industries, including:

• Automotive – engine gasket manufacturing.
• Construction – vibration protection for foundations and machinery.
• Gas industry – sealing elements used in valves and fittings.
• Wood processing – production of sound-reducing plywood panels.
• Footwear – orthopedic insoles.
• Electronics and electrical engineering – spacing materials in power systems and vibration insulation for transformers.
