GPPS-123 is a general purpose polystyrene grade with a good balance between flow characteristic and improved heat resistance.



SECCO-GPPS-123 iis a general purpose polystyrene grade with a good flow characteristic and improved heat resistance. It is well balanced in its flow characteristic and heat resistance so preferably used for injection molding. It can be extruded as blend component with high impact grades and as a gloss layer for thermoformed foils and sheets.


S2040 complies with the hygiene standards for polypropylene resins used in food packaging specified in GB9693-1988, the requirements of the United States Food and Drug Administration (FDA) 21CFR 177.1520(c) 1.1(a), and the requirements of the European Union’s RoHS directive. However, it is the responsibility of the user to verify whether their final product complies with the regulatory
