Material Notes:

LACQRENE® 2901 is a very easy flowing, medium impact polystyrene for injection molding. The very high flow of this grade allows for the production of thin wall section or long flow path molding on single or multi impression tooling. It is particularly recommended for the production of models. The excellent fluidity and ease of coloring of 2901 finds applications in the production of colored masterbatches giving excellent distributive properties.ApplicationModels, Office equipment - filing trays, Closures, Boxes and lids, Pen bodies, MasterbatchesInformation provided provided by Total Petrochemicals.Total Petrochemicals includes former Fina and Atofina plastics product lines.
