CORKRUBBER PRODUCTS


CorkRubber products offer many of the advantages of rubber
compounds, along with the added benefit of controlled compressibility and recovery. The addition of cork granules to the compound helps to decrease the amount of flow or creep that occurs in compounds that are only made with rubber. This also creates a better distribution of load when compression occurs between bolt spans.

Due to the variations of the cork content in similar rubber compounds there are different density grades that can be manufactured. This process can produce material as compressible as cork to non-compressible as straight rubber or fibre products. This benefit allows for a wide variety of sealing applications from dust covers to automotive valve covers to industrial radiators.

CorkRubber grades are manufactured with a variety of compounds including Neoprene, Nitrile, Ethylene acrylic, Polyacrylate, SBR and Silicone. This provides the necessary sealing features such as fluid or temperature resistance. In Electrical Transformers, the resistance to the several types of oils commonly used is obviously of primary importance, and the ability to seal the entire range (from small distribution to large power transformers) on a long-term basis demonstrates versatility of our materials.
