1540(GPPS1540)

GPPS

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. This grade has food contact approval. Application: Packaging articles,petri dishes,office equipments,pen barrels,crisper boxes for refrigerators,cups,food containers gloss layer coextrusion.anionic styrene butadiene copolymer dilution.
