Asbestos joint sheet
Asbestos joint sheet is made of good long asbestos fiber, 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 motorcycles, agricultural machinery, engineering machinery engines it widely used as the sealing gasket material for the equipment in kerosene, petrochemical, alkali, acid, solvent, fuel oil, petroleum-based lubricating oil and other mediums.
We can supply temperature from 150 degree up to 600 degree. Max size 1500 x 4000 mm from thickness 0.4 mm - 6.0 mm.
