A fireproof, compressible, intumescent, elastomeric material useful to seal expansion joints, curtain wall gaps and penetrations in floors and walls in order to prevent the passage of flame and smoke. A seal of the material retains strength before and after exposure to fire and provides superior resistance to the impact, erosion, and cooling effects of a hose stream used to combat a fire. The composition of this compressible, fireproof material consists of elastomers, vulcanizing agents, fillers, softening agents, and an intumescent. This fireproof material may be in cellular or noncellular form with various degrees of compressibility and softness. It can be produced in sheets, molded parts, and continuous length strips. It may be vulcanized or nonvulcanized.
