Luban 6147 HDPE is high-density polyethylene with broad molecular weight distribution and high molecular weight. This product provides an excellent combination of extrudability and parison stability, which contribute to uniform wall thickness in large parts. The grade is ideal for blow molding containers such as the 5 - 55 gallons (20 - 210 liters) closed-head shipping containers and other similar parts. The broad distribution also provides outstanding environmental stress crack resistance (ESCR) at good rigidity. The smooth surface of molded parts is readily treated and printed for high-quality applications.
