DescriptionPan Carbon FeltPre-fire / Heat-treated Temp: 2192℉ | 1200℃Grade: Carbon FeltWhat is Pan Carbon? Pan Carbon felt, also known as Polyacrylonitrile, is a specialized refractory insulation material manufactured for high-temperature vacuum and inert gas furnaces, among other applications. Our pan felt is available in carbon and graphite grades that have been pre-fired / heat treated to promote consistent insulation performance, higher purity, and reduced ash content. Felt grades can be purified to less than 10 ppm if needed. Material is rated for temperatures up to 5432℉ (3000℃). Our pan carbon grade is pre-fired to 2192℉ (1200℃), whereas our pan graphite grade is pre-fired to 3992℉ (2200℃).Pan Vs Rayon Felt Pan is manufactured with larger courers fibers resulting in lower surface area and better oxidation resistance. The flexible material is stiffer and less soft to the touch but offers great performance at reduced price. For heat treat applications, our office highly recommends pan carbon felt due to the materials handling ease, performance, and reduced price. If operating at temperatures ≥ 3272℉ (1800℃), please use rayon carbon felt as the thermal conductivity is lower than pan.Benefits of Pan Carbon FeltFlexible material that is easy to cut and installLower surface area and better oxidation resistanceMinimize energy consumption and costMaximize furnace performance and longevityHigh purity and high thermal resistanceLow ash and sulphur contentLow density, shrinkage, and thermal massApplicationsFurnace insulation & partsHeat shields & sinksBacking strips for soldering & weldingCathode in flow battery applicationsReaction surface for other electrochemical processesGlass blowing pads & plumber padsWicks in ultralight stovesAutomotive exhaust liningsThermal insulatorsPropertiesPropertiesUnitPan CarbonPan GraphiteDensityg/cc0.140.13Carbon Content%≥ 97≥ 99.9Ash Content%≤ 0.75≤ 0.05Tensile StrengthMPa0.180.12Thermal Conductivity 2012℉ | 1150℃ W/mk 0.12 0.16Temperature Rating1℉ | ℃5432 | 30005432 | 3000Pre-fire temp℉ | ℃2192 | 12003992 | 2200Stock SizingStandard1/8"x48"x80' 1/4"x48"x80' 1/2"x48"x43'1/8"x48"x80' 1/4"x48"x80' 1/2"x48"x43'Alternate SizingStandard | MetricContact usContact usNotes:1Temp Rating in Vacuum or Inert Atmosphere Documents Technical Data Sheet Safety Data Sheet
