备注说明 | SGM-025 is a certified prime grade High Molecular Weight specially developed for both INJECTION MOLDING and EXTRUSION applications requiring high heat resistance, high tensile strength, and high stiffness. SGM-025 offers good-flow processability, good dimensional stability and excellent clarity of molded articles. SGM-025 applications include foamed sheet extrusion for packaging e.g. egg trays, sheet extrusion for shower cabin panels, dinnerware, oriented polystyrene (OPS) for cookie and cake trays, thin-walled containers, and consumer electronics. SGM-025 complies with FDA regulation 21CFR 177.1640 and with most international regulations concerning the use of Polystyrene in contact with food articles. |
