Abstract Low density polyethylene (LDPE) and its blends with styrene butadiene rubber and ethylene propylene diene monomer were cured, using electron beam irradiation as well as dicumyl peroxide (DCP). The effect of blending was found to change the melt viscosity when compared with the virgin LDPE. Also, the influence of curing system on the various properties was investigated. It was found that either irradiation or DCP curing enhanced the gel content and crosslink density as well as the mechanical and hot set properties. The obtained data showed that the curing greatly influence the stress strain and hot set properties, in which there is a variation in such properties for both curing methods in spite of the gel contents were comparable.
