POLYSTYRENE CRYSTAL 1540 is an easy flowing crystal polystyrene designed for extrusion or injection applications. In extrusion, it allows to increase extruder output and thermoforming cycle times when mixed with a high impact polystyrene such as POLYSTYRENE IMPACT 7240. Having high gloss, it is particularly suitable for glossy-layer co-extrusion. In injection moulding, POLYSTYRENE CRYSTAL 1540 with this low viscosity at high shear rate has a good injectability and combines an excellent fluidity with a higher softening point.

Main applications are dairy sheet, cups (dilution with impact polystyrene)

Injection: Boxes, office equipment - e.g. filing trays, CD boxes, pen bodies, internal fridge parts, toys, cups
