Study Of Devulcanized Natural Rubber as The Green Impact Modifier for Polypropylene With Electron Beam Irradiation

The effects of DVC composition, EB irradiation and UV source degradation in relation to the performance of the PP DVC compound were investigated. Various DVC compositions (0 phr 20 phr) were compounded with PP and irradiated at several dosages (0 kGy 200 kGy) und er natura l weathering condition (0...
