DescriptionCarbon Insulation BoardsPre-fire / Heat-treated Temp: 2192℉ | 1200℃Grade: Carbon Board, Rigidized Pan FeltWhat are Carbon Insulation Boards? Carbon Insulation Boards, manufactured from rigidized pan felt, are used as refractory insulation for vacuum or protective atmosphere process furnaces. Material is pre-fired to 2192°F (1200°C) to promote higher purity, reduced ash content, and consistent performance. Ash purification services to ≤ 10ppm available. The rigid insulation boards can be easily cut or machined to custom sizes and used in both square and round hot zones. Boards manufactured from pan have better oxidation resistance and lower surface area due to its larger courser fibers in comparison to graphite insulation boards manufactured from rayon.Surface & layering Options Materials such as Graphite Foil, Carbon Fiber Composite (CFC), and GraphiSeal can be used to enhance the perforamnce of our carbon boards. 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 Carbon Insulation BoardsBoards able to be fabricated into complex shapes & machined to printGraphite 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)Greater oxidation resistance & lower surface area due to larger courser fibers in comparison to rayonApplications of Carbon Insulation BoardsVacuum FurnacesPowdered Metal SinteringAnnealing & Hot PressingSilicon / GaAs Crystal Growing FurnacesSputtering TargetsFiber Optics ProductionCVD, CVI, and CVR FurnacesGraphite Purification FurnacesCarbon Fiber Heat Treating FurnacesPropertiesPropertiesUnitsCarbon Insulation Boards (Pan)Densityg/cm30.18Carbon Content%≥ 95Specific Resistanceohm.cm0.18 - 0.22Ash Contentppm≤ 500Ash Content Purifiedppm≤ 10Temperature Rating1℉| ℃5432 | 3000Pre-fire temp℉| ℃2192 | 1200Standard Size Boardinches40" x 60"Max Size Boardinches60" x 60"Max Thicknessinches≤ 20"Alternate Sizing & PuritiesStandard | MetricContact usNotes:1Temp rating in vacuum or inert atmosphereDocuments Technical Data Sheet Safety Data Sheet
