General purpose polystyrene
Product Description
GPPS1540 is an easy flowing crystal polystyrene designed for extrusion or injection applications. It improves extruder output and thermoforming cycle time when mixed with a high impact polystyrene such as HIPS7240.It is particularly suitable for glossy-layer coextrusion.
Applications:
packaging articles, petri dishes, office equipments, pen barrels, crisper boxes for refrigerators, cups gloss layer coextrusion. anionic styrene butadiene copolymer dilution.
