Recycling of waste materials is a field of great attention in all industries. Reclaiming, retreading and using the energy by heating have been empolyed for recycling the waste tires. Recycling on the other hand involves incorporation of small particles obtained from the discarded tires. Rubber sheet using the waste tire grinded scrap which is called "crumb rubber" was prepared and investigated in this study. The effect of the size of the crumb rubber on the properties of the crumb/polyurethane blend was studied in parallel with the optimum binder content content for good mechanical properties. Also this paper covered the effect of fillers on the mechanical properties of the blends. The deformation patterns of the crumb rubber/polyurethane sheet were predicted by finite element analysis. The predicted behaviors were consistent with experimental results. Therefore, this numerical works will be useful to effectively design elastomeric components.
