Beschreibung
Zusammenfassung:	A polystyrene (PS) composition for making an extruded foam, the PS composition comprising polystyrene, a blowing agent, and an additive selected from glycerol monostearate (GMS), glycerol tri-stearate (GTS), mineral oil (MO), epoxidized soy oil (ESO), epoxidized polybutadiene, or combinations thereof. Methods of producing a low density polystyrene (PS) foam are also provided. L'Invention concerne une composition de polystyrène (PS) permettant de fabriquer une mousse extrudée, la composition de PS comprenant du polystyrène, un agent d'expansion et un additif choisi parmi le monostéarate de glycérol (MSG), le tri-stéarate de glycérol (TSG), l'huile minérale (HM), l'huile de soja époxydée (HSE), le polybutadiène époxydé, ou des associations correspondantes. L'invention concerne également des procédés de production d'une mousse de polystyrène (PS) de faible densité.
