The material is formed by integrating graphite paper, carbon felt and carbon cloth, and then subjecting them 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 temperature etc. Properties: Density: 1.45 to 1.75g/cm3 Carbon Content : 99% Temperature: 3,600 degrees Max Size of tube/drum: Diameter: 200mm ~ 1,500mm Thickness: 30mm ~ 120mm High: 300mm ~ 2,000mm we can supply you: 1. Soft Graphite felt (Pan & Rayon based) 2. Rigid Graphite felt board 3. Carbon-Carbon Composite(CFC) 4. Insulation cylinder (Graphite felt & CFC)
