摘要： A thermally-expandable sealant for joints, cavities or holes, which foams in the event of a fire and thereby effects a seal, comprising as a carrier a fleece or fabric made of glass or plastic, which is coated with a composition based upon expandable graphite and containing, per 100 parts by weight of expandable graphite, 10 to 30 parts by weight of polychlorobutadiene, 1 to 40 parts by weight of an alkylphenol/formaldehyde resin and 1 to 3 parts by weight of stabilizers known per se, and optionally, up to 30 parts by weight of inorganic fibers and up to 80 parts by weight of aluminium hydroxide. A process for sealing joints, cavities or holes using the sealant is also disclosed.
