Asbestos Free(Non-Asbestos Gasket) Ecological
Metal Jacket Gasket and Joint Sheet Gasket

Metal jacket gaskets are used for various high temperature lines such as power plants, boilers, engines, chemical plants, petrochemical plants and others because of its high sealing performance. But asbestos is prohibited to use now in many countries. NAPI(R) is made of zero-asbestos material. So NAPI has both high performance gasket function and environmental friendly function. (Conform to ISO Regulation EC 1272/2008 CLP/EC Note Q)

Why is NAPI safety packing?
NAPI(R) use fine zero-asbestos material "ZERO-AS BOARD(R)" not non-asbests material for inner material. "ZERO-AS BOARD(R)" is basically made from biosoluble inorganic fiber, so the asbestos content ratio of "ZERO-AS BOARD(R)" is almost 0% !! (less than 0.0001% by EPA method)
