Improvement in the radiation stability of synthetic elastomer epdm modified with metallic selenium

This study presents the antioxidant effects induced by metallic selenium in ethylene- propylene terpolymer (EPDM) subjected to accelerated ageing by γ-irradiation. Several doses were applied up to 100 kGy in order to qualify this material for nuclear applications. Three concentrations (0.25, 0....
