Abstract For prediction of tensile strength combine aged NR/CR blends, samples with ratios 100/0, 95/5 and 90/10 were subjected heat aging at various temperatures, namely 100, 110 120°C, each for 22 h, followed by dynamic loadings to 140 % frequency 300 cycles/min. Then the strengths defined. Based on obtained experimentally values experimental statistical model was built using FORTRAN language. The result in equation NR blends low CR (not higher 10 %) contents. This seems have fine usability, having relative error between calculated defined less than considered range experiments.
