摘要：
An intumescent fire seal comprises ceramic or like fibres mixed with exfoliating graphite and/or sodium silicate in granular and/or powder and/or chip form. The fire seal may comprise a non-woven mat or sheet, a block or other shaped product and may be enveloped wholly or partially in metallic foil or the like. Alternatively, the fire seal may comprise a liquid or paste which can be applied directly to a surface to be fire proofed.
