The invention relates to a composition, especially for an elastomer body of an elastic coupling, comprising the following components:—polyisoprene rubber having a proportion of 20 to 30% by weight,—butadiene rubber having a proportion of 20 to 30% by weight, based in each case on the total weight of the composition. The invention further relates to the use of the composition for production of an elastomer body, especially for an elastic coupling, preferably elastic shaft coupling. The invention additionally relates to an elastomer body, especially for an elastic coupling, which comprises the composition. The invention also relates to a coupling comprising the composition or the elastomer body. 1.
