Flame-retardant foam slabs are based on styrene polymers wherein from 1 to 12% by weight of expanded graphite and also, if desired, from 1 to 12% by weight of a phosphorus compound are present as flame retardants.

Flame-proofed polystyrene foamed materials

Expandable styrene polymers containing recycled polystyrene have a content of recycled material of up to 40% by weight, based on the total weight of the polystyrene, wherein, in the course of the polymerization of the reaction mixture, from 100 to 500 ppm of a molecular weight regulator and/or from 0.05 to 1.0% by weight, based in each case on the polymerization solution, of a finely divided polyethylene wax are added.

Foam boards produced using halogen-free blowing agents

Production of foam boards of high compressive strength from styrene

Foam boards of high compressive strength are produced by extruding a mixture of a styrene polymer and from 5 to 16% by weight of a blowing agent which contains

Production of foam boards of high compressive strength using a blowing

Foam sheets of high compressive strength are produced by extruding a mixture of a styrene polymer and from 5 to 16% by weight of a blowing agent mixture containing

Production of foam sheets of high compressive strength

Foam sheets of high heat distortion resistance contain a) from 80 to 99% by weight of a styrene polymer and b) from 1 to 20% by weight of poly-1,4-phenylene sulfide, and, if desired, conventional additives and are produced by extrusion using a low-boiling blowing agent.

Foam sheets of high heat distortion resistance
