POLYSTYRENE CLARIFIED BLEND AND METHOD FOR MAKING SAME

摘要

A polystyrene copolymer blend product that that achieve an optimal combination of haze/clarity, strength, toughness/snap, and organoleptic properties. The polystyrene copolymer blend product includes a first layer including about 2 weight percent to about 6 weight percent of a total weight percent of the product, wherein the first layer further includes about 95 weight percent to about 100 weight percent of GPPS or HIPS, and a second layer including about 98 weight percent to about 94 weight percent of the total weight percent of the product, wherein the second layer further includes about 23 weight percent to about 40 weight percent of GPPS, from about 55 weight percent to about 70 weight percent of SBC, and from about 0 weight percent to about 15 weight percent of HIPS.
