Polyethylene of raised temperature resistance(PE-RT)for pipes,P4406R2 was developed in high density polyethylene plant which applies Hostalen ACP technology.P4406R2 and market-avai lable PE-RT resins were characterized by universal material testing machine,differential scanning calorimeter,and gel permeation chromatography.The results show that P4406R2 performs excellently in mechanical and heat-resistance,it contains more high molecular weight sections and owns wider molecular weight distribution,which enable it to be processed into both small caliber pipes for floor heating and big caliber pipes for heat supply.
