The present invention is concerned with the field of polymer chemistry and 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 object of the invention is that in particular 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 object is attained by rubber or elastomer compositions that 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. In the methods according to the invention, at least one rubber and at least 20 to 150 phr of a phase change material in solid or liquid form are used, the composition is mixed 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.
Rubber or elastomer compositions containing at least one rubber or elastomer matrix and at least 20 to 150 phr of a phase change material in solid or liquid form, wherein the phase change material has a particle size of ≦1 μm, and wherein one or more auxiliary materials can be present.
A method for the production of rubber compositions, wherein at least one rubber and at least 20 to 150 phr of a phase change material in solid or liquid form are used, wherein phase change material with a particle size of ≦1 μm is used, wherein one or more auxiliary materials can be used, the composition is mixed or the at least one rubber is at least brought into contact with the phase change material with or without auxiliary materials, and further processing steps can be performed.
A method for the production of elastomer compositions, wherein at least one rubber and at least 20 to 150 phr of a phase change material in solid or liquid form are used, wherein phase change material with a particle size of ≦1 μm is used, wherein one or more auxiliary materials can be used, and further processing steps can be performed, and either the phase change material is mixed with the at least one rubber and subsequently vulcanized, or the at least one rubber is mixed with or without one or more auxiliary materials and vulcanized without, or after completion of, further processing steps and subsequently at least brought into contact with the phase change material.
