耐热聚乙烯(PE-RT)管材

Polyethylene Pipe of Raised Temperature Resistance

耐热聚乙烯(PE RT)管材既具有普通聚乙烯管材的性能如:可熔接性、可回收再利用及成型加工、施工方便等特点,还具有接近交联聚乙烯管材的长期耐热性能,同时它还具有独特的柔韧性,是一种节能、环保型的塑料管材。对耐热聚乙烯(PE RT)管材的原料、成型方法、性能及应用情况作了简要论述,主要通过与其它管材(热水用)的静液压试验比较认识PE RT管材。

Polyethylene pipe of raised temperature resistance has the properties of common polyethylene pipes,such as melt weldability,recyclability,convenient manufacture and assembly etc,as well as long term hot resistance approaching crosslinked polyethylene (PEX) pipes and flexibility.It is a kind of plastics pipe of energy saving and environmental protection.The resins,processing method,properties and applications of polyethylene pipe of raised temperature resistance are summarized.Polyethylene pipe of raised temperature resistance is compared to other pipes for hot water systems by hydrostatic test.
