Product Description:
General purpose polystyrene GPPS 1115 with the easy flow and good clarity. It is recommended for applications where a specific balance of flow and strength are important. In injection moulding, GPPS 1115 possesses low viscosity at the high shear rates. It is particularly suitable for glossy-layer co-extru-sIOn.
Application:
Injection moulding, disposable cups, pen barrels, crisper boxes for refrigerators, food containers, gloss layer co-extrusion, loose fill packaging and it can blend with HIPS.
