Abstract

Co-vulcanizates which have good mechanical properties, a good resistance to oil, an effective flame resistance and a low smoke gas density are obtained from mixtures of (a) from 95 to 5% by weight of EVA rubber and (b) from 5 to 95% by weight of elastomers which contain nitrile groups and have from 25 to 140 nitrile groups and less than 35 double bonds per 1000 carbon atoms, by radical cross-linking.
