The Contribution of BaTiO to the Stability Improvement of Ethylene-Propylene-Diene Rubber: Part II-Doped Filler.

The thermal and radiation stabilities of the formulations based on ethylene-propylene-diene rubber (EPDM), which contain barium titanate (BaTiO) doped with lanthanum and cerium oxides, were investigated by chemiluminescence and mechanical testing. The contributions of these doped fillers are related to the surface interaction between the structural defects (doping atoms, i.e.

The Contribution of BaTiO to the Stability Improvement of Ethylene-Propylene-Diene Rubber: Part I-Pristine Filler.

This study presents the functional effects of BaTiO powder loaded in ethylene-propylene-diene rubber (EPDM) in three concentrations: 0, 1, and 2.5 phr. The characterization of mechanical properties, oxidation strength, and biological vulnerability is achieved on these materials subjected to an accelerated degradation stimulated by their γ-irradiation at 50 and 100 kGy.
