DOW™ LLDPE DNDA-7340 NT 7
LLDPE
陶氏化学(Dow Chemical)
产品描述
DOW DNDA-7340 NT 7 Linear Low Density Polyethylene (LLDPE) Resin offers outstanding flex life, toughness and environmental stress crack resistance (ESCR) and is well-suited for use in blow molding applications such as small, squeezable bottles, as well as, extruded flexible hoses and, tubing. Offering high melt strength, excellent toughness and outstanding ESCR, DOW DNDA- 7340 NT 7 LLDPE resin also is well-suited for use in large blow molded parts, such as drum liners. Additionally, It may also be used in certain sheet and tubing applications where these properties are also important.
