Material Notes:

8350 is a very high impact polystyrene for extrusion. This grade has an improved environmental stress crack resistance in comparison with standard high impact grades. It is proposed for the production of packaging intended for products likely to cause stress cracking, e.g. fats and oils. LACQRENE® 8350 retains good mechanical properties at low temperatures making this grade suitable for frozen packaging and for the production of fridge liners.ApplicationSheet for thermoforming and high quality printing, Cabinet and door liners for fridges, Packaging for use at low temperatures, Packaging for aggressive foodstuffs.Information provided provided by Total Petrochemicals.Total Petrochemicals acquired former Fina and Atofina plastics product lines. This product was previously known as LACQRENE®
