Patent application: Rubber or elastomer compositions and processes for their manufacturing

Ben Welter - Thursday, November 30, 2017

U.S. patent application 20170342240 (applicant Leibniz Institute for Polymer Research Dresden, Germany):

"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."
