高密度聚乙烯

    高密度聚乙烯（HDPE)管材，系采用高密度聚乙烯树脂经挤出机挤出而成，产品抗老化，强度高，耐磨性能好。同时具有优异的耐腐蚀、耐冲击、耐低温、自润滑、流阻小等性能，适用于供水、制药、化工、排污、沙浆等腐蚀性介质的输送及高层建筑的雨水管等。规格与FRPP管相同，使用温度-20℃+70℃
    我单位也可根据客户要求生产超高分子量的聚乙烯管材和燃气、埋地聚乙烯管材、管件。

    HDPE pioe materials use HDPE resin are made by high pressing. The products have many traits such as resistance ageing, high strength, good resistance to abrasion. As well as this trait, the pipe materials have some excellent comprehensive traits such as resistance to corrosion impact and low temperautre, self-lubrication, small flowing. The products can be used to transport such as supply water, pharmacy, chemical industry, metallurgy and sewage disposal, some corrosive mediums. such as mortar etc. and can be used to high construction water pipes. The specifications of HDPE pipe materials are the same as FRPP. The using tempatrue are -20℃+70℃.
