PS Resin GPPS-525
GPPS-525 is a general-purpose polystyrene injection grade designed for transparent and rigid molded products. It offers good clarity, dimensional stability, rigidity, and consistent processing performance.
Description
GPPS-525 is a general-purpose polystyrene injection grade supplied as transparent pellets. It provides good clarity, rigidity, dimensional stability, and processing performance for clear and rigid molded products.
The grade offers suitable flow for standard injection-molding applications and supports the production of parts requiring a clean surface appearance and consistent molded-part quality.
Applications
Typical applications include housewares, transparent containers, disposable cutlery, drinking cups, toys, stationery products, hangers, cosmetic casings, refrigerator components, lamp covers, and other rigid injection-molded products.
Packaging
GPPS-525 is generally supplied in 25 kg bags. Jumbo-bag packaging, including approximately 750 kg bags, may also be available depending on the manufacturer and current supply arrangement.
Final packing format, palletization, and container-loading quantity should be confirmed at the time of order.
