要約
(EN)
Expandable polystyrene-type resin particles produced by granulating a polystyrene-type resin containing a foaming agent, wherein the polystyrene-type resin has a weight average molecular weight (Mw) ranging from 120,000 to 320,000, the foaming agent contains butane in an amount of 2 to 8 parts by mass relative to 100 parts by mass of the polystyrene-type resin, and the composition of the above-mentioned butane comprises isobutane and normal butane at a proportion (isobutene:normal butane) ranging from 10:90 to 80:20 by mass.
(FR)
L'invention concerne des particules de résine de polystyrène expansibles constituées par une résine de polystyrène comprenant un agent d'expansion mise sous forme de particules. La masse moléculaire moyenne en poids (Mw) de la résine de polystyrène, est comprise dans une plage de 120000 à 320000. L'agent d'expansion comprend en proportion 2 à 8 parties en masse de butane, pour 100 parties en masse de résine de polystyrène. La composition dudit butane est telle que, selon un rapport en masse, le rapport isobutane : butane normal est compris dans une plage de 10 : 90 à 80 : 20.
