Creep Resistance of Polyethylene - PE80 has excellent …

Polyethylene molecules demonstrate very similar characteristics as Polybutene-1 molecules at temperatures below around 60 C. The molecular bonds become weaker at elevated temperatures, which in turn severely reduce creep resistance at higher temperatures, making Polyethylene an unsuitable material for the manufacture of hot water pluing systems.
