产品描述
UNIVAL™ DMDC-6150 NT 7 High Density Polyethylene (HDPE) Resin 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. UNIVAL DMDC-6150 NT 7 HDPE resin is ideal for blow molding containers such as the 5-55 gallon (19-212 liter) closed head shipping containers and other similar parts. The broad distribution also provides outstanding environmental stress crack resistance (ESCR) at a good rigidity. Because of these characteristics, 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. The smooth surface of molded parts is readily treated and printed for high quality applications.
Main Characteristics:
Excellent environmental stress crack resistance
Excellent parison melt strength/low sag
Good extrudability/processability
Good rigidity
Complies with:
U.S. FDA 21 CFR 177.1520 (c) 3.2a
Canadian HPFB No Objection (With Limitations)
European Commission Regulation (EU) No 10/2011
