Cross linking of high density polyethylene (HDPE) was first performed via high energy
10 Mev electron beam (EB) irradiation. HDPE was also cross linked with
Dicumyle peroxide (DCP).The gel content of samples was determined by solvent extraction.
Degree of cross linking was evaluated by hot set apparatus; as well .In order to clarify the effect
of nature of cross linking, correlation of electrical properties such as volume resistively,
dielectric constant, dielectric strength with the type of cross linking system was made. It was
found that, in the same amount of gel content, electrical properties of samples cross linked by the
two methods, differed.
