Graphite sheet Graphite Coils

Graphite sheet Graphite Coils Expanded Graphite sheets roll, Firm resistance to high or low  temperature, radiation as well as to corrosion excellent  self-lubricity, low friction coefficient, unusual flexibility and  resiliency. Being widely used in kinetic and static sealing for machine,  pipe pump and valve in power industry, oil industry, chemical industry,  light industry as well as machinery industry. Graphite paper roll is an  ideal new type of sealing material which can replace traditional sealing  materials rubber and fluorated plastics and as asbestos, etc.   Item                                                Unit                           Value Tolerance of density                        g/cm3                       -0.06~+0.06 Tolerance of thickness                     mm                          -0.06~+0.06 Carbon content                                %                             99 Tensile strenght                               MPa                          4.5 Compressibility                                 %                            ≥40 Recovery                                          %                            ≥10 Sulphur content                                ppm                         ≤ 1100 Chlorine content                               ppm                         ≤ 45 Temperature(in oxidizing atmosphere ) oC                          -200~600 ....
