Research and application status of polyethylene of raised temperature resistance pipe and resin at home and abroad

介绍了耐热聚乙烯管材的分类,概述了国外耐热聚乙烯管材专用料的发展现状以及主要Ⅰ型和Ⅱ型树脂的性能,同时阐述了国内耐热聚乙烯管材专用料新标准的制定情况和开发情况,并针对国内的研发和生产现状,对存在的问题和发展方向提出了相应的建议。

In this paper,the types of polyethylene of raised temperature resistance（PE-RT） pipes were introduced. Then the develop situation of PE-RT pipes special materials at abroad was summarized and the performance characteristics of the main type I and type II resins were described. And the formulation of the new Chinese national standard and the research status of PE-RT pipes were reviewed. At last,the existing problems were discussed and some suggestions were put forward.
