HDPE RESINS FOR USE IN PRESSURE PIPE AND RELATED APPLICATIONS

机译:用于压力管道的HDPE树脂及相关应用

摘要

The present invention provides bimodal polyethylene resins in which the highmolecular weight ethylene copolymer component typically has a relativelynarrow molecular weight distribution, with short chain branching content beingsubstantially constant across its molecular weight distribution. The resins ofthis invention are typically characterized by improved toughness andresistance to slow crack propagation properties making them useful forpressure pipe applications.
