Rigid graphite felt material is formed by inteerating graphite paper, carbon felt and carbon cloth, and then qubjecping then to secondary high temperature purification treatment. The material is superior in ablation resistance performance, thermal shock resistance performance, airflow washing proof performance and thermal insulation performance. It is mainly used for vacuum high pressure air quenching furnace, low pressure fritting furnace, pressurization vacuum sintering furnace etc. Properties: Materials PAN-CF Bulk Density: 0.22~0.25g/cm3 Carbon : ¡Ã99% Thermal Conductivity(1,150 degrees):0.20~0.30 W/mk Resistivity :55-60¦¸mm2/m Bolding Strenght :1.5~3.2 MPa Flexure Strength:1.0~2.5 MPa Ash PPm ¡Ã200 Processe Temp:1,800oC Size: Length:1,500 ; 1,800 mm Width:1,000 ; 1,300 mm Thickness: 20--400mm Working temperature under vacuum or inert gas: ¡Ã1,800 £¬¡Ã3,200 degrees we can supply you: 1.
