Abstract: A rubber mixture includes natural rubber, butadiene rubber, styrene-butadiene rubber, synthetic polyisoprene or ethylene-propylene-diene rubber or a blend of two or more types of rubber, filler, crosslinking system and recycled rubber particles. The recycled rubber particles may be biotechnologically modified. The addition of the modified rubber particles can improve the physical properties of rubber mixtures and the lifetime of engine mounts or bushings. The biotechnical processing of the vulcanized rubber and the use of the high-quality modified rubber particles in new mixtures can distinctly reduce the amount of waste and the amount of CO2 emitted by virtue of the use of recyclate and can increase the proportion of recycled material in the product. The disclosure further provides for the use of rubber mixtures for industrial rubber products, such as engine mounts and bushings.
