Cork Gaskets and Sheeting

Cork Gaskets were once a major product for the Gasket Industry. Today, Cork materials have now been superseded by ‘higher-tech’ materials in many applications.  Thirty years ago the majority of sump gaskets in cars were made from Neoprene Cork. Manway gaskets for liquid storage tanks would be made from the same material.

Today, many applications that used cork have now changed to more specific materials to increase efficiency and minimise cost.

Cork – being a natural product, depends on regular harvesting and a regular weather pattern. The trees are grown mostly in the temperate zone of the Northern Hemisphere. Cork trees are found in countries such as Portugal, Spain, France, Italy and North Africa.

The material for Cork gaskets is normally an agglomerate of particle compressed into blocks using binders including urethanes and rubbers. Each blend offers different properties however the granulated cork in each sheet gives its own unique resilience to the material. Today it is certainly a material that should not be overlooked and is one that EAS Ltd still use in abundance.

Cork Sheeting

Our sheet material is all made from block, slit to thickness with an extremely fine finish. The material can be sanded for extra fine tolerance where required. Continuous coil production up to 50mts is available for narrow width materials. This is  especially useful in the transformer industry where gaskets are typically dovetailed.
