PE-RT 管材及管件
PE-RT管俗称耐热聚乙烯（pe-rt ）管，PE-RT管是采用中密度聚乙烯（mdpe）与辛烯聚合而成，耐高温抗冻性能是pe-rt管的特点。PE-RT管颜色为原材料本色即透明色，不加任何色母及填充料。
PE-RT管应用范围
我国PE-RT管道在建筑内冷热水管道领域的应用发展很快，原材料也有了进一步的发展。2002年，行业标准《冷热水用耐热聚乙烯（PE-RT）管道系统》发布，但是由于当时行业标准参照的是德国标准《耐热聚乙烯（PE-RT）管道——一般质量要求》和《耐热聚乙烯(PE-RT)管道——尺寸》，这两个标准都是基于I型PE-RT材料的性能指标编制的。随着材料的发展，II型PE-RT材料的性能指标已经远远高于第一代材料，国际标准ISO22391《冷热水用耐热聚乙烯（PE-RT）管道系统》也已经完成修订更新，增加了II型PE-RT管道的要求。[1]
随着材料的发展，PE-RT管进行更新升级为PE-RTⅡ型管，按其共聚单体不同分为三种：
1.乙烯与辛烯共聚-耐热聚乙烯(C2+C8)；
2.乙烯和己烯共聚-耐热聚乙烯(C2+C6)；
3.乙烯和丁烯共聚的耐热聚乙烯(C2+C4)
目前已经推出（PE-RT Ⅱ型管）材料，适用于工业用及民用建筑冷热水管路系统、饮用水系统、热力预埋管、地面辐射采暖系统以及高温地源热泵系统等，尤其在北方应用于城镇供热系统二次管网-PE-RT II型预制直埋保温管。
