The effect of recycled silicone catheter (rSC) loading (5, 15, 25, 35 and 50phr) with two different size; fine and coarse size, on tensile properties (tensile strength, modulus at 100% elongation and elongation at break) and morphology of recycled silicone catheter filled Standard Malaysian Rubber (SMR L/rSC) vulcanizates were studied. For tensile properties, tensile strength and modulus at 100% elongation (M₁₀₀) for both SMR L/rSC fine and coarse vulcanizates show increment up to 15 phr and decreased gradually as the rSC loading increased. The drop might be due to the formation of agglomeration of rSC within the vulcanizates. Meanwhile, elongation at break (E_B) decreased with increasing rSC content. Comparison between SMR L/rSC fine and coarse vulcanizates indicates that SMR L/rSC fine vulcanizates has better tensile properties than SMR L/rSC coarse vulcanizates due to better dispersion and filler-rubber interaction. The results obtained also show that the morphology of SMR L/rSC fine vulcanizate is better than that of SMR L/rSC coarse vulcanizates. This attributed to better incorporation between rSC fine and SMR L rubber matrix.
