Rubber hydrohalide films of increased elasticity are obtained by using as plasticiser a mixture of alkyl or alkoxy-alkyl ester of phthalic acid and an alkyl, alkoxy-alkyl or aralkyl ester of a dicarboxylic of the formula COOH.(CH2)n.COOH where n is at least two, e.g. adipic or sebacic acid. In an example, 10 to 20 parts of dibutyl phthalate and 10 to 20 parts of dibutyl sebacate are used.
