 Vitreous or Glassy carbon is a form of pure carbon produced by the thermal decomposition of a three-dimensionally crosslinked polymer. It has high flexural strength. The zero open porosity gives a low permeability to gases. Glassy carbon has excellent resistance to a wide range of aggressive chemical environments and can, therefore, be used as an alternative material to precious metals for laboratory equipment and, for example, for electrodes in polarography.

Vitreous Carbon Foam has an open pore structure and extremely high porosity, giving a high surface area and low resistance to fluid flow. It is chemically inert in non-oxidising environments over a wide temperature range, maintains strength at high temperatures and is thermally insulating yet electrically conducting. Applications include use as porous electrodes, thermal insulation, filtration, substrate support, and acoustic control.

Please enquire for other foams having different thicknesses, porosities, and sizes.
