| GS-025 is a High Molecular Weight certified prime grade specially developed for use in foamed sheet extrusion for packaging applications. GS-025 is designed for injection molding and extrusion applications requiring high tensile strength, high heat resistance and high stiffness. GS-025 offers good-flow processability, good dimensional stability and excellent clarity of molded articles. GS-025 complies with FDA regulation 21CFR 177.1640 and with most international regulations concerning the use of Polystyrene in contact with food articles. |
