Abstract

The present invention relates to rubber or elastomer compositions as can be used for vehicle tires, and to a method for the production of the rubber or elastomer compositions. The elastic modulus of the compositions can be adapted depending on the temperature and/or the application conditions, and is a cost-effective and easily implemented method for the production of the compositions. The rubber or elastomer compositions contain at least one rubber or elastomer matrix and at least 20 to 150 phr of a phase change material in solid or liquid form. The compositions may be made by mixing the at least one rubber and the at least 20 to 150 phr of a phase change material in solid or liquid form, or the at least one rubber is at least brought into contact with the phase change material, and further processing steps can be performed, and a vulcanization can be performed.
