Supagraf® Plain

Supagraf Plain is available as a standard and an ultra‑pure graphite foil gasket material.

  • General industry
  • Nuclear

Supagraf Plain is a premium quality 98% pure exfoliated graphite foil with an oxidation inhibitor and contains no binders, fillers or elastomers.

Supagraf Plain Ultra-High Purity is a 99.8% pure exfoliated graphite foil with low sulphur, low leachable chlorides and low leachable fluorides which are beneficial features for sealing materials used in nuclear power generation plants.

  • 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.
