DescriptionPan Graphite FeltPre-fire / Heat-treated Temp: 3992℉ | 2200℃Grade: Graphite FeltWhat is Pan Graphite? Pan Graphite 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 graphite grade is pre-fired to 3992℉ (2200℃), whereas our pan carbon grade is pre-fired to 2192℉ (1200℃).Pan Vs Rayon Felt Pan is manufactured with larger courser 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 a reduced price. Our office highly recommends pan graphite felt due to the materials handling ease, performance, and reduced-price in comparison to rayon graphite felt. If a lower ash content and thermal conductivity are needed, use rayon graphite felt.Benefits of Pan Graphite 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 massNo outgassingApplications of Pan Graphite FeltFurnace 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 AtmosphereDocuments Technical Data Sheet Safety Data Sheet
