It is made of special non-asbestos heat-resisting fibre, heat-resisting packing material and nature rubber compound heating and compression molding it. Substitution of corresponding models of asbestos rubber sheet, it is used for the equipment in water, steam, etc. And it is used as sealing material in the joints of pipeline.
