UNIVAL™ DMDC-6145 NT 7
HDPE
陶氏化学(Dow Chemical)
产品描述
UNIVAL™ DMDC-6145 NT 7 High Density Polyethylene (HDPE) Resin provides good parison stability, which contributes to uniform wall thickness in large parts, making it ideal for blow molded containers ranging from, 5-15 gallon (9-57 liter) tight-head pails to 30-gallon (114 liter) drums. Containers molded from this resin offer outstanding environmental stress cracking resistance (ESCR) and excellent rigidity. The appearance of finished blow molded parts made from this resin is excellent.
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)
