Extrusion and injection moulding grade LDPE Granules

Extrusion and Injection Moulding Grade LDPE Granules are a form of low density polyethylene (LDPE) plastic available in 12 variations. LDPE can be customized for different applications that take advantage of its properties like flexibility, toughness and chemical resistance. The granules make LDPE easy to use in manufacturing processes like extrusion and injection molding to produce plastic products like containers, tubes, caps, films and more. The wide range of variations available allows manufacturers to select the optimal LDPE grade for their specific application and processing method.
