FIELD: chemistry.
SUBSTANCE: invention relates to methods of foaming thermoplastic polymer granulates. Description is given of thermoplastic polymer granulates which are capable of foaming, chosen from styrene polymers, containing: from 5 to 50 wt % filler, chosen from a group containing talc, chalk, kaolin, aluminium hydroxide or glass beads; from 2 to 40 wt % intumescent graphite with average particle size in the range 10 to 1000 mcm; from 0 to 20 wt % red phosphorous or organic or inorganic phosphate, phosphate or phosphonate; from 0 to 10 wt % soot or graphite.
EFFECT: reduced flammability, improved fire resistance.
