Effect of the Mixing Time on the Homogenity and Mechanical Properties of Rubber Mixture

Rubber compounds consist of group of initial materials mixed together then molded by compression to produce the final product. The effect of mixing time on the homogenity and mechanical properties for rubber compound type (MCG) was studied in this research. The samples under research were prepared in Jaber Bin Hayyan company. Using the roller and the mixer. The homogenity was studied using the idea of nuclear radation absorption while the mechanical properties was studied using the (Tera test ) instrument. In this study it was found that the best time of mixing is (6) mint. using the mixer and (20) mint. using the roller.
