More Information
Summary:The rubber compounds according to the present invention are based on uncrosslinked rubbers, crosslinked rubber particles together with multifunctional isocyanates and polyols. These rubber compounds can be used for the manufacture of rubber vulcanizates or any type of molded rubber article, whereby the vulcanizates display good mechanical properties combined with a large difference in impact resilience values at 70° C. and 23° C.
