Gaskets and Sheet Jointings
Supagraf® Laminated N7
Sheet jointing of 98% pure exfoliated graphite with a bonded central layer of 13µm thick nickel foil. Sheets thicker than 2.0mm have two layers of metal foil and three of graphite.
- Extra strength for ease of handling and fitting.
- Excellent sealing integrity.
- Can be cut with hand tools.
(Typical values for 1.5mm thick sheet)
Density (graphite), Mg/m³: 0.7
Compressibility, %: 45 (ASTM F36A)
Recovery, %: 17 (ASTM F36A)
Maximum temperature (oxidising media): +400°C
Maximum temperature (*inert/reducing media): +1000°C
Minimum temperature: -200°C.
(*Ensure that temperatures above +400°C on atmosphere side of flange do not cause gasket to oxidise inwards from the outside edge.)
Precision cut gaskets to any shape, size and quantity. In sheets: 0.5m x 1.0m, 1.0m x 1.0m. Thicknesses: 1.0mm, 1.5mm, 2.0mm, 3.0mm.
