Intumescent, electrical installation systems which comprise an injection molding material of polyolefins or polyimides in combination with intumescent additives, the melting points of the polyolefins and of the polyimides being lower than the intumescence temperature of the intumescent additives.

Intumescent electrical installation systems and processes for their production

Coextruded, intumescent fire-protection strips jacketed on three sides, obtained by coextruding an intumescent composition composed of a thermoplastic elastomer with a processing temperature of not more than 250&deg; C. selected from the class consisting of block copolymers and uncrosslinked thermoplastic polyolefins, sulfuric-acid-treated graphite, flame retardant, and an inorganic additive which forms an enamel or forms a ceramic, and a three-sided jacket, where appropriate in association with a chambered profile, made from a thermoplastic elastomer with a processing temperature of not more than 250&deg; C. selected from the class consisting of block copolymers and uncrosslinked thermoplastic polyolefins, flame retardant, and, where appropriate, a color pigment, where the fire-protection strips may be designed either as a hot-gas seal or else as a combined cold- and hot-gas seal with spatially separated functions.
