The tensile and oxygen depletion properties of EVA resins blended with varying compositions of iron (Fe), modified iron (MFe) and/or ascorbic acid (Vc) oxygen scavengers were systematically investigated. Oxygen depletion experiments clearly suggest that the oxygen depletion rates of modified iron powders filled E MFe series samples are much faster than those of E vc and E Fe series samples filled with the same weight loadings of ascorbic acid and pure iron powders, respectively. After blending Vc together with MFe oxygen scavenger compounds in the EVA resins, a "synergistic" effect on the oxygen depletion properties of the E VcMFe samples was observed when the weight ratios of Vc to MFe oxygen scavengers are between 3/7 to 5/5. Further tensile experiments show that, E Fe and E MFe series samples always exhibit significantly higher of and e f values than E vc series samples filled with the same oxygen scavenger contents. In fact, the σ f and e f values of the E VcMFe series samples increase significantly as their Vc loadings present in oxygen scavenger compounds reduce. In order to understand these interesting oxygen depletion and tensile properties of E Vc , E Fe , E MFe and E VcMFe series samples, SEM and EDX analysis of the compositions on the surfaces of E VcMFe series samples were performed. Possible mechanisms accounting for these interesting oxygen depletion and tensile properties of E Vc , E Fe , E MFe and E VcMFe series samples are proposed.
