Non-Asbestos Gasket is a general purpose sheet material reinforced with high-grade asbestos- free fibers and bonded with heat-resistant nitrile rubber.
It has excellent anti-stick performance on both sides. It is a good alternative to compressed asbestos gasket.
The gasket is suitable for engineering, auto mobile, chemical, oil & gas, petro chemical, power generation, paper, glass & ceramic, sugar, steel, smelter, boiler, pharmaceutical, Marin and all applications where needs higher temperature and pressure resistance and where non-critical gaseous and liquid media have to be sealed off.
