Graphite extruded board has similar
performance with extruded board. Graphite isadded in the production process of extrudedboard to make fire-resistant polystyrene foamboard. By utilizing the unique properties ofgraphite such as high temperature resistance.nigh strength, chemical stability. and plasticitythe thermal conductivity of the product canbe reduced to 0024W/(mk).Improved thefire resistance of the product, increasedits compressive strength and dimensionastability. Applicable to 75% of building energyefficiency standards.
