Material Notes:
Good extrudability/processability Complies with U.S. FDA 21 CFR 177.1520 (c) 3.2a UNIVAL™ DMDA-6147 NT 7 is a polymer 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. DMDA-6147 NT 7 HDPE resin is ideal for blow molding containers such as the 5-55 gallon closed head shipping containers and other similar parts. The broad distribution also provides outstanding environmental stress crack resistance (ESCR) at a good rigidity. These characteristics mean a wide variety of products, such as industrial chemicals, latex paints, printing inks, foodstuffs, adhesives, and other chemical specialties may be packaged in containers produced from this resin.
