Flexible graphite sealing rings flexible graphite sealing rings types: varied kings of pads and rings specifications: varied kings of standard parts or special processed NARTs natural graphite powder is mainly used for refractory materials, anti-oxidation coating materials for smelting furnaces, thermal insulation materials, stabilizers for industrial pyrotechnics, desulfurizers for smelting industry, catalysts for fertilizer industry and production of pencil leads. Flexible graphite products have excellent sealing performance, with rebound rate of 20-30%, compression rate of 25-31%, no softening point and melting point of 3790 ℃. The friction coefficient is very low (0.08-0.12), which is resistant to acid and alkaline corrosion, so it can meet the requirements of mechanical seals. Products include flexible graphite plate, flexible graphite sealing ring, flexible graphite packing, flexible graphite corrugated belt, etc.
