Technical Datasheet 1540
Product Description:
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.
Applications:
- Extrusion: Impact dilution; Gloss layer in co-extrusion; Anionic styrene butadiene copolymer dilution.
- Injection: Packaging articles; Medical applications, eg, Petri dishes; Office equipment; Pen barrels; Crisper boxes for refrigerators; Cups.
