产品描述
DOW DNDB-7441 NT 7 Linear Low Density Polyethylene Resin is produced using UNIPOL™ process technology. It is intended for use in hose and tube applications. It also has utility in gasketing, spiral wound hose, and corrugated hose applications. It exhibits good draw down, excellent resistance to melt fracture, low temperature toughness, uniform matte surface finish, and exceptional flex life. It has a modulus (stiffness) that is 50% higher than that of a conventional high pressure, low density polyethylene resin of equal density. It is especially well suited for profile extrusions where stress cracking resistance, flexural wear resistance, and ease of extrusion are important. It is also recommended as a modifier in blends with flexible copolymers such as ethylene ethyl acetate (EVA) and ethylene ethyl acrylate (EAA) to enhance their rigidity in extrusion applications.
