GPPS1540 is an easy flowing crystal polystyrene designed for extrusion or injection applications . In extrusion , it improves extruder output and thermoforming cycle times when mixed with a super high impact polystyrene such as HIPS7240. It is particularly suitable for glossy-layer co-extrusion.It does combine excellent fluidity with a higher softening point than GPPS1810/1811 grade.
Application:
- Packaging articles
- Petri dishes
- Office equipments
- Pen barrels
- Crisper boxes for refrigerators
- Cups
- Food containers gloss layer co extrusion and anionic styrene butadiene copolymer dilution
