产品描述
DOW DMDA-8007 NT 7 High Density Polyethylene (HDPE) Resin is a narrow molecular weight distribution high density homopolymer designed to offer excellent stiffness, low warpage, good/acceptable toughness, and good moldability. This resin is ideally suited for injection molded crates, cases, trays, tote bins, and other objects requiring high rigidity. This resin is also suitable for cast film extrusion processing.
Excellent stiffness/modulus
Excellent warp resistance
Molded parts have high gloss, low odor
For injection molded crates, cases, totes, and other parts needing high modulus
Complies with U.S. FDA 21 CFR 177.1520 (c)2.2
Complies with Canadian HPFB No Objection
Complies with EU, No 10/2011
