Cork rubber sheet is a sealing material made from natural cork and rubber. It combines the compressibility of cork with the flexibility and resilience of rubber. This combination makes it suitable for gaskets, vibration damping, noise reduction and industrial sealing where a soft, compressible and durable sheet is required.
The material is supplied in sheet and roll form, and can be cut to thickness and width according to your specification. It is used for engine gaskets in automobiles, tractors and ships, as well as for petroleum pipes, transformers and electrical equipment.
The table below compares the Medium and Hard grades. Use it to select the correct hardness, density, tensile strength and compressibility for your sealing application.
