A polystyrene (PS) composition for making an extruded foam, the PS composition comprising: a dried PS/alumina compound comprising a PS and an alumina additive, wherein the dried PS/alumina compound has a moisture content, measured by Coulometer, that is less than or equal to about 0.05 weight percent (wt %); and a blowing agent.

Pre-dried polystyrene/alumina compound for foam extrusion

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.
