Total Lacqrene® 7240 High Impact Polystyrene

Subcategory: Polystyrene; Thermoplastic

Close Analogs:

Total Petrochemicals now includes former Fina and Atofina plastics product lines.

Material Notes:
LACQRENE® 7240 is a very high impact polystyrene for the extrusion industry. This grade has been designed to be diluted with crystal polystyrene (such as LACQRENE® 140, 1340 or 1540) at higher levels than could be achieved by some comparable high impact polystyrenes. The good melt strength of this grade makes it particularly suited for deep-draw thermoforming.

Application

Dairy sheet, Fill, Seal, Individual dairy pots, Multilayer sheets, Cups, Food trays, Egg boxes
