The Study of Mechanical Properties and Morphology of Recycled Nitrile Glove Filled Epoxidized Natural Rubber Compounds (NBRr/ENR25)

Abstract:

The effects of mechanical properties (tensile properties and resilience test) and morphology of recycled nitrile glove (NBRr) filled epoxidized natural rubbers (ENR25) were examined. Two different size ranges of NBRr particles, i.e., S₁ (250μm-500μm) and S₂(2cm-5cm) were used in this study. The NBRr/ENR25 compounds with five different compositions of NBRr (5, 15, 25, 35 and 50 phr) were prepared using a two roll-mill at room temperature. The result indicated that the tensile properties such as tensile strength and elongation at break decreased as the ratio of NBRr increased. Meanwhile stress at 100% elongation show an increasing trend with the addition of recycled nitrile glove in ENR25. The resilience properties of NBRr/ENR25 compounds decreased when NBRr loading increased. The scanning electron microscopy studies showed that the fine size, S₁ of NBRr particles in NBRr/ENR25 compounds illustrated a better NBRr-ENR25 matrix interaction compared with coarse size, S₂ of NBRr particles. The results overall indicated that the NBRr/ENR25 with fine size, S₁ of NBRrparticles show better mechanical properties (tensile properties and resilience properties) and morphology compared to coarse size, S₂ of NBRr particles.
