Material Notes:
1540 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 high impact polystyrene. Having high gloss, it is particularly suitable for glossy-layer co-extrusion. In injection molding, 1541 possesses low viscosity at high shear rate. It combines excellent fluidity with a higher softening point. 1540 is not externally lubricated.ApplicationDairy sheet, Cups, Coextrusion crystal. 1541 Extrusion: Boxes, Petri dishes, medical products, Office equipment - e.g. filing trays, Pen bodies and toys, Internal fridge parts.Information provided provided by Total Petrochemicals.Total Petrochemicals acquired former Fina and Atofina plastics product lines. This product was previously known as LACQRENE®
