Kaxite Sealing manufactures asbestos rubber sheets in eight standard grades: KXB150, KXB200, KXB250, KXB300, KXB350, KXB400, KXB450 and KXB510. The sheets are made from asbestos fibre, rubber and heat-resisting packing material, compressed into thick paper. They are used for water, steam and pipeline joint sealing, and for equipment sealing in industrial plants.
Working pressure is 1.5 MPa and max working temperature is 150°C. Standard sizes include 4600 x 1500 mm, 4100 x 1500 mm, 3800 x 2700 mm, 2000 x 1500 mm, 1500 x 1360 mm, 3810 x 1270 mm, 1270 x 1270 mm and 1500 x 1500 mm, with thickness 0.3–6.0 mm. Custom sizes, OEM services, bulk discount and free samples are available. Send your size, grade and quantity for a firm quotation.
Asbestos rubber sheets are compressed jointing sheets made from asbestos fibre, rubber and heat-resisting packing material. The material is compressed into thick paper and supplied in sheet form for cutting into gaskets, flange seals and equipment joints. They are widely used for water, steam and pipeline joint sealing, and for general industrial equipment sealing.
Higher KXB grades provide higher tensile strength and higher heat and pressure resistance. Use the grade chips below to compare the standard range before you send your enquiry.
