General Information :
GPPS 1540 is an easy flowing crystal polystyrene designed for
extrusion or injection applications . In extrusion , it improves extruder
output and thermoforming cycle time when mixed with a super high
impact polystyrene such as HIPS 7240. It is particularly suitable for
glossy-layer co-extrusion.
It does combine excellent fluidity with a softening point higher
than GPPS 1810/1811 grade.
Applications :
Extrusion :Impact dilution; Gloss layer in co-extrusion; Anionic
styrene butadiene copolymer dilution.
Injection :Packaging articles; Medical applications,e.g., petri
dishes; Office equipment; Pen barrels; Crisper boxes for refrigerators;
Cups.
