Rubber Cork Sheet

The buoyance of natural cork is used to good effect in petrol and oil level gauges, but the most important application of cork in the automotive industries is in cork-and-rubber gaskets. Today, these are as essential as petrol or diesel fuel to the car and truck industries. The material used combine the compressibility and resilience of cork with the high mechanical strength and dimensional stability of rubber, making them the best substances of such automotive applications as oil pan gaskets, valve cover gaskets and timing gear cover gaskets. Another important application of cork-and-rubber is as a seal to retain lubricants in crank shaft bearings when pressure is applied, the air within cork cells is compressed, thus exerting a reverse pressure on the restraining faces. This is termed 'fight back' and is a primary requirement in all good gasket materials. Cork-and-rubber can be cut easily, and because it is strong and flexible, it can be used for making gaskets with narrow flanges. A wide variety of formulations used for making gaskets with narrow flanges. A wide variety of formulations using different types of rubber like Natural Rubber, Synthetic Rubber, Nitrile, Neoprene, EPDM Silicone and sizes of cork granuals are available to meet the industry's various requirements. Cork in Electrical Industry Special cork-and-rubber have been developed to prevent leakage of the very searching cooling fluids used in modern electrical transformer, similar material are also widely used in switch gear circuit breakers, lightning arresters, and other transmission equipment, as well as in conduit fittings, gear cases and cover plates in washing machines.

TYM stock 2 grades that meet most of our customers requirements they are tym1120 and tym1521

1521 is a highly compressible synthetic based cork suitable for low and medium bolt pressure,with good flexability and resilience,it also has good oil and fuel resistance making this an ideal cork for the automotive industry

1120 is a dual-binder formulation(Neoprene/Nitrile) whick gives excelent sealing performance in mineral oils,it is also good for ozone ageing and cracking.Approved for use with BS148,Midel 7131 and Silicone Oils

Other binders and electrical grades are available on request

we can supply this product in either sheet form,strip form plain or sab or cut gaskets to your requirements



most grades of cork will maintain its flexibility down to -25c and can withstand operating temperatures of +100 to 110c below is a rough guide to cork Air,Water, Water/Glycol, Alcohols, Fuel/Diesel Oil, Lubricating Oils-Mineral, Hydraulic Oils are all fine with Nitrile/Neoprene binders. Lubricationg Oil-Synthetic are fine with a Nitrile binder only Water/Oil Emulsion use a special blend of Nitrile/Neoprene/Butyl
