E Modulus of PE
The E modulus of polyethylene varies with temperature, duration of loading, stress, and the particular grade of material.
However, in order to facilitate engineering calculations, it is generally appropriate to group materials into categories and adopt ‘typical’ values of E.
The Tables below list E values in MPa for PE80 and PE100.
Typical E Values for PE pipes (MPa)
