This improved packing material is made of a flexible graphite sheet (of 1mm or less thickness) which is cut into a 5 mm or smaller width and surface covered with a fibre. The packing material is made of 1-10 flexible graphite sheets which are laminated and covered with fibres selected from among metal fibres such as stainless steel, inorganic fibres such as asbestos, ceramics, glass fibres and carbon fibres, and organic fibres suich such as cotton, rayons, phenols, PBI, PTFE, PPS etc. The covering fibres can be surface-treated with graphite powder, silicon oil, a rubber adhesive or PTFE The surface of the covering fibres can be treated with Zn or NaNO2 as an anticorrosive. The flexible graphite sheets can be laminated with reinforcing fibres or foil and then covered with fibres to form the packing materials. The reinforcing fibres are of the same type as the covering fibres. The foil is selected from among metal foils such as Zn, Cu, Al or nonmetal foils such as pulp sheet, PTFE sheet, PEI sheet etc. Rod-shaped packing materials can be obtained by mixing graphite particles with at least one material chosen from short fibres, rubber, resin, or lubricant and then covering with fibre. |
