A moldings material (MM) for the production of intumescent fireproof mouldings comprises a combination of: (A) a thermoplastic elastomer or thermoplastic ethylene-vinyl acetate (EVA) copolymer; (B) a phosphorus-containing fire retardant; and (C) expanding graphite. Independent claims are also included for : (a) extruded or injection molded parts produced from (MM); (b) a method for the production of extruded parts by feeding (A) into a twin screw compounder-extruder, melting (A), adding a mixture of (B) and (C) and extruding the material as strips; and (c) a method for the production of injection mouldings or screw-pressed parts by premixing the above components, melt-processing at up to 160 degrees C and injection moldings or screw-pressing the material obtained. |
