Effects of Recycled Silicone Catheter Filled Epoxidised Natural Rubber (ENR 50) on Tensile Properties and Morphology

Abstract:

The effect of recycled silicone catheter (rSC) on tensile properties (tensile strength, modulus at 100% elongation and elongation at break) and morphology of recycled silicone catheter filled epoxidised natural rubber (ENR 50/rSC) vulcanizates were studied in loading range of 0 to 50 phr with two different size; fine (300-600μm) and coarse (1-2 cm). For tensile properties, tensile strength, modulus at 100% elongation (M₁₀₀) and elongation at break (E_B) for both ENR 50/rSC fine and coarse vulcanizates show increment up to 15 phr but then decreased as the rSC content increased. Comparison between ENR 50/rSC fine and coarse vulcanizates indicates that ENR 50/rSC fine vulcanizates has better tensile properties than ENR 50/rSC coarse vulcanizates due to better dispersion and filler-rubber interaction as proven in morphological study. The results indicate that the morphology of ENR 50/rSC fine vulcanizate is better than that of ENR 50/rSC coarse vulcanizates in which fine rSC well bonded with ENR 50.
