Cork rubber sheet is retained with cork’s ageing resistance, oil resistance, low temperature resistance, high coefficient of friction, good compressibility and also has the high elasticity of rubber used and share of tensile strength.Makes the product has good mechanical properties, physical properties and chemical properties. The cork rubber sheet’s medium resistance is similar to rubber.The material of cork rubber sheet do not contain asbestos, so it’s belong to green products, can satisfy the requirements of certain equipment exports.According to add different products ,sheets products are divided into nitrile butadiene rubber, neoprene and butyl benzene types.There are both moulded type and cutting type.
Application
Widely used as for flange sealing duties with oils,fuels and water in the electrical,automotive,marine and general machinery sectors.
