DESCRIPTION

An asbestos free sheet sealing material combining graphite, aramid fibres and a rubber binder.

SERVICE

Graftec material is suitable for a wide range of applications including: hot and cold water,low pressure steam, oils, fuels, gases and a wide range of general chemicals. Suitable for public utilities, chemical plants, oil industry, etc.

Max recommended temperature : SHORT TERM 300°C
Max recommended temperature : OPERATING STEAM 250°C *
Max recommended pressure : 10MPa / 100 BAR / 1500 PSI.

These temperature and pressure guides cannot necessarily be used simultaneously and may not apply to all thicknesses. The operating temperature for non-asbestos sheet materials is related to the thickness of the material. Thinner materials offer better temperature and pressure properties.
