DESCRIPTION
An asbestos free, high performance compressed sheet sealing material, based on a blend of aramid and inorganic fibres and special additives, with a high quality nitrile rubber binder system.SERVICE
A superior performance material with excellent mechanical properties. It is suitable for many applications including: gases, fuels, oils, mild acids, solvents and high pressure steam and oxygen. Suitable for public utilities, water treatment plants and chemical plants etc.Max recommended temperature : SHORT TERM 440°C
Max recommended temperature : OPERATING 350°C
Max recommended temperature : OPERATING STEAM 220°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.
