Asbestos Rubber Sheets -sealing gasket material for the equipment

Oil-Resistance Asbestos Rubber Sheets

Natural Rubber Sheet is with good physical, mechanical characters and insulation property.Work in the environment with the high requirement of the electrical modulus at the temperature of
-35°C~+100°C in the dry air. Natural sheet can be applied to produce the buffer ring and seals, o-ring, rubber gasket, etc. It has excellent abrasion resistance, soldering resistance,excellent elastic ability and sealing.
Material:
Made of good long asbestos Fibre, oil-resistance synthetic rubber, heat-resisting packing material compound heating and compression molding it and used as sealing material in the joints of oil pipeline and sealing gasket used on automobiles motorcvcles, agricultural machines, engineering machinery engines
