摘要： The present invention relates to an inexpensive material and method of making the material having superior heat insulation capacity for use in furnaces and other apparatus. The method comprises grinding flexible graphite foil, preferably recycled material, to a small particle size, thermally shocking the particles to expand them, mixing the expanded graphite with a thermoset phenolic resin, heating the mixture under pressure to form a solid sheet and then heat treating the solid sheet. The present invention also includes a method for making a plastic material by using a thermoplastic material mixed with re-expanded graphite. The compound of thermo plastic material and re-expanded graphite is fed into an injection molding system at a relatively high temperature and injected into a mold where a plastic material is formed. The plastic material is then removed from the mold when the material is still very hot but hard set.
