Compressed Fiber
SF 3300
A premium quality sheet material reinforced with a blend of aramid and glass fibers and bound with nitrile rubber. SF 3300 complies with the highest grade of the British Standard for non-asbestos sheet sealing materials - BS 7531 Grade X. For applications in split case pumps where a thin, complex gasket capable of withstanding a high surface stress is required, SF 3500, a variant of SF 3300, has been developed.
Where caustic liquors have to be sealed a variant of SF 3300 reinforced with a blend
of aramid and carbon fibers is offered: this material, SF 5000 is widely used in the pulp and paper industry.
