Kaxite's asbestos rubber sheets are premium sealing materials manufactured from high‑quality asbestos fiber, rubber compounds, and heat‑resisting packing materials – compression‑molded into thick, durable sheets. As a leading Asbestos Gasket Sheets Supplier in China, we produce these industrial rubber sheets in eight performance grades (KXB150, KXB200, KXB250, KXB300, KXB350, KXB400, KXB450, and KXB510) to meet a wide spectrum of sealing requirements – from general water and steam pipeline joints to high‑temperature industrial equipment. With a working pressure of 1.5 MPa and maximum temperature of 150°C, our sheets deliver reliable sealing performance in demanding environments. Available in a comprehensive range of sizes including 4600×1500mm, 4100×1500mm, 3800×2700mm, 2000×1500mm, 1500×1360mm, 3810×1270mm, 1270×1270mm, and 1500×1500mm, with thicknesses from 0.3mm to 6.0mm.
