DescriptionGraphite Insulation BoardsPre-fired / Heat-treated Temp: 3632℉ | 2000℃Grade: Graphite Board, Rigidized Rayon FeltWhat are Graphite Insulation Boards? Graphite Insulation Boards, manufactured from rigidized rayon felt, are used as refractory insulation for vacuum or protective atmosphere process furnaces. Material is pre-fired to 3632°F (2000°C). This premium material is pre-fired at higher temperatures, has a higher carbon content, lower ash content, and lower thermal conductivity in comparison to carbon insulation boards made from pan. Ash purification services to ≤ 20ppm available. The rigid insulation boards can be easily cut or machined to custom sizes and used in both square and round hot zones.

Foil and CFC can be used on exterior surface(s) or layered internally.Graphite foilDust generation preventionSurface protectionLow gas-permeabilityIncrease radiant heat retention while reducing issues with furnace contaminant containmentDecreases pump downtimes and increases longevity of the insulationCarbon Fiber Composite (CFC)Dust generation preventionHigh strength and surface protectionPromotes excellent durability, impact, & wear resistanceGraphiSeal CoatingReduce porosity and dustingImprove oxidation resistanceSurface(s) and/or edge(s) can be sealed with specified number of coatsMaterial can be mixed with Silicon Carbide powder to produce an anti-eutectic coatingBenefits of Graphite Insulation BoardsBoards can be fabricated into complex shapes & machined to printGrapite Foil option available on surface(s) or layeredCFC option available on surface(s) or layeredGraphiSeal Coating option available on surface(s) and/or edge(s)Carbon Content ≥ 99%Ash purification servces to ≤ 20ppm availableCustom machining and fabrication availableApplications of Graphite Insulation BoardsVacuum FurnacesPowdered Metal SinteringAnnealing & Hot PressingSilicon / GaAs Crystal Growing FurnacesSputtering TargetsFiber Optics ProductionCVD, CVI, and CVR FurnacesGraphite Purification FurnacesCarbon Fiber Heat Treating Furnaces
