This paper will demonstrate combination of optimum response for Tensile strength and Time curing which are obtained by combining elastomer, filler and co-accelerator at optimum level factors is the best way to overcome defect products. Data from this study will be obtained from 15 direct experiments based on RSM by using box-behnken designMinitab 18 and response optimization was performed to get optimal response value combination from the expected target response. The analysis shows that all factors including elastomer, filler and co-accelerator have significant effect on tensile strength and time curing responses. The best composition to get the optimal combination of responses from certain response limits is elastomer = 70PHR, filler = 30PHR, and co-accelerator = 1.47PHR. The optimum value for tensile strength response is 15 kg/cm2 and time curing is 3.5 minutes. Beside as a solution for this problem, this optimization will increase production capacity of rubber strap 12.5% more that the factory decide to decrease production line and choose market development strategy to overcome access production and labor to new product base on polyurethane. Keywords―Optimization, Tensile Strength, Time Curing, Response Surface Methodology, Box-behnken, Regression Analysis.
