    摘要: PURPOSE:Polystyrene foam sheet that contains fillers and rubber components at specific ratios to the base resin, thus being suitable for economical fabrication, because of its small stacking height, high molding cycle and good profiling. CONSTITUTION:A polystyrene resin is used as base polymer, 5-40wt% of a filler such as talc and 0-20wt% of rubber component such as butadiene rubber based on the base polymer are contained, and an appropriate amount of a foaming agent such as butane are added, then they are extruded into sheets, thus producing the objective polystyrene foam sheets suitable for use in fabrication with a bulk density of 0.15-0.7g/cm , a thickness of 0.3-2.0mm., a gas amount of less than 0.3mol/kg remaining in the foaming agent, a draw ratio of less than 1.25. USE:Insertion type covers, interior packing material for cake or candy, incubation vessels.
