DescriptionGraphite Foil RollsTemperature Rating: In vacuum – 5432℉ | 3000℃ In steam – 1562℉ | 850℃ In air – 950℉ | 510℃Grade: Standard or High Purity RollsBenefits of Graphite Foil Rolls High purity material with excellent thermal stability and reflectivity. Resistant to temperatures of 510℃ in air, 850℃ in steam, and 3000℃ in a vacuum (or reducing). Chemically inert with pH range of 0-14 (except strong oxidizers such as nitric or sulphuric acid). Low coefficient of friction and self-lubricating. Asbestos-free and no associated health hazards Low electrical resistivity and high thermal conductivity. Highly anisotropic. Electrical and thermal properties different parallel to and perpendicular to flakes. Excellent in-process longevity – minimize replacement and downtime costs. Easy to cut and shape. Machine to print available for gaskets and seals.Applications of Graphite Foil Rolls Thermally conductive gasket, seal, or liner, while being heat and chemical resistant. Release foils in glasswork and hot presses. EMI (electromagnetic interference) and chemical shield. Thermal management and heat dissipation liner. Cathodes for electrolysis of liquids. Dry sheet lubricant, stress sensing, vibration damping, spark plasma sintering (SPS) and other thermal electronic or electrochemical applications.PropertiesPropertiesUnitsStandard PurityHigh PurityNuclear GradeCarbon Content�99.799.9Sulfur Contentppm1000300< 200Chloride Contentppm45100Ash%1.00.50.0Densityg/cm³1.01.01.0Tensile StrengthMpa4.55.56.5Compressive StrengthMpa180200220Compressing Modulus0.0120.0120.0Recovery%> 10%> 10%> 10%Specific ResistanceμΩ-m5710Compatible pHpH0-140-140-14Max Temp in Air℃510510510Max Temp in Steam℃850850850Max Temp in Vacuum℃300030003000AvailabilityIn StockIn StockSpecial Order Only
