GON525 General Purpose Polystyrene is a highly transparent GPPS grade with 8 MFI medium melt flow. It delivers excellent mechanical and heat resistance properties, alongside easy processability and short cycle times.
Crystal transparent GPPS resin, perfect for tumblers, jewelry boxes and consumer packaging. It supports cap-layer coextrusion to upgrade surface gloss for better visual performance.
Possesses balanced structural strength and thermal stability, delivering stable durability for household and packaging structural parts.
8 MFI medium melt flow grade, compatible with injection molding, extrusion and thermoforming. Suitable for multi-cavity molds to achieve short molding cycles, higher output and lower production costs.
Safe to use in all food direct contact packaging applications.
