   In this work, rubber magnetic composites were prepared by incorporation of hard strontium hexaferrite in rubber blends based on polar and non-polar matrices. The aim was to investigate the influence of applied filler on magnetic and mechanical properties of rubber composites. Strontium ferrite was dosed in various concentrations in order to obtain the optimal characteristics of prepared materials. The results demonstrate that the presence of strontium ferrite in rubber matrices leads to significant increase of magnetic characteristics of composites. The mechanical properties of tested systems seem to be less dependent on the magnetic filler content, although the improvement of evaluated mechanical properties with doping content of ferrite was recorded.
