ABSTRACT:
Gasketing material is produced by combining a tubular casing of braided or woven from continuous inorganic filaments, such as alumina-boria-silica fibers, with a core composition comprising a major proportions of intumescent material, suitably unexpanded vermiculite. Heating the gasket in situ results in expansion to give a resilient gasket stable to temperatures of about 1000.degree. to 1200.degree. C.
