产品描述
UNIVAL™ DMDC-6143 NT 7 High Density Polyethylene (HDPE) Resin is a polymer with broad molecular weight distribution and high molecular weight polymer. This product provides good stability, which contributes to uniform wall thickness in large parts, making it ideal for blow molding of containers, such as the 5-30 gallon (19-114 liter) tight-head pails, and other large parts. The broad molecular weight distribution of this resin contributes to the outstanding environmental stress crack resistance (ESCR), good rigidity level and extrudability it offers.
Outstanding 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
Complies with Canadian HPFB No Objection (With Limitations)
Complies with EU, No 10/2011
