产品描述
DOW DFDA-7059 NT 7 Linear Low Density Polyethylene Resin is an ethylene-butene copolymer which is supplied in pelleted form. It is generally recommended for slot cast thin film applications requiring both clarity and toughness. It is excellent in coextruded, slot cast stretch wrap. This resin is also suitable for use in hose and tube applications.
Main Characteristics:
• High clarity • High tensile strength • High elongation • Good puncture resistance
Complies with:
• U.S. FDA 21 CFR 177.1520(c) 3.2a • EU, No 10/2011 • Canadian HPFB No Objection
