100%的非石棉衬垫材料

Non-asbestos sealing materials incorporate flat metal sheet as a core after processing with vulcanization and bonding technologies. Reinforced with carbon steel, non-asbestos composite sheet has outstanding performance for applications in the working environment of corrosion, high temperature and dynamically stressed. The short duration maximum temperature is up to 400°C (750°F).
