The Effect of Electron Beam Irradiation on HDPE/EPDM Blends with Triallyl Cyanurate

摘要

Blends formed of 80 wt% of high-density polyethylene (HDPE) and 20 wt% of ethylene-propylene diene monomer (EPDM) have been added with 3 wt% of triallyl cyanurate (TAC). The thermal and mechanical properties were followed up as a function of e-beam irradiation dose. The results obtained that the values of gel contents, decomposition temperature, tensile strength, and impact strength increase with increasing irradiation dose up to 100 or 150 kGy and then decreased. Additionally, the effect of cross-linking agent of TAC was observed in upgrading of various properties. An irradiation dose of 150 kGy is suitable to obtain optimum conditions of thermal and mechanical properties, respectively.
