100%的非石棉衬垫材料

This is a composite sheet which incorporate non-asbestos sealing materials and perforated or flat metal sheet, either as a core or facing after processing with vulcanization and bonding technologies. The product contains NBR and aramid fiber with good compressibility and recovery, and small stress relaxation. The short duration maximum temperature is up to 400°C (750°F). WAG-TL1310 combines non-asbestos material and perforated carbon steel as a core.
