Supagraf^® Plain

• Compatible with media in the range pH 0-14
• Sulphur content (typical): ≤300 ppm
• No loss of volatiles at high temperature
• Lower limiting temperatures apply when used with oxidising agents, e.g. nitric acid
• Thermal conductivity, ring of density 1.4 g/cm3: (SG 1.4): axial: 400 W/mK; radial: 6 W/mK

• Can be used as filler material for manufacturing spiral wound gaskets
• Sealing layers for semi-metallic cores like kammprofile gaskets, corrugated metal cores and fillers for metal clad gaskets
• High-temperature steam, demineralised water, heat transfer media, petroleum products, inorganic and organic acids, alkalis, hot waxes and oils
• Piping flange gaskets, valve bonnets, and OEM equipment

• Maximum temperature: +450°C (+842°F)
• Minimum temperature: -196°C (-321°F)
• Maximum pressure: 5 MPa/50 bar (750 psi)

• Precision cut gaskets to any shape, size or quantity
• In sheets: 1 m x 1 m, 0.5 m x 1 m
• Sheet thicknesses: 1.0 mm, 1.5 mm, 2.0 mm,3.0 mm
• Rolls up to 60 m long; width 1.0 m
• Roll thickness: 0.5 mm

The operational life span of graphite at high temperatures might be limited due to media or environmental influences. Please contact us for continuous exposure in oxidising environments above +450°C.
