Patent number: 10435543Abstract: 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.Type: GrantFiled: May 19, 2017Date of Patent: October 8, 2019Assignee: LEIBNIZ-INSTITUT FUER POLYMERFORSCHUNG DRESDEN E.V.Inventors: Tamil Selvan Natarajan, Amit Das, Klaus Werner Stoeckelhuber, Rene Jurk, Hai Le Hong, Sven Wiessner, Gert Heinrich

Patent number: 10414920Abstract: An elastomeric composition that has a high tensile strength and high hardness is produced by a method that is cost-efficient and easy to carry out. The object is attained by an elastomeric composition that contains at least one base elastomer, at least one hydrophilic polymer, and at least one inorganic salt. The object is furthermore attained by a method for producing an elastomeric composition in which at least one rubber, at least one hydrophilic polymer and at least one inorganic salt are mixed and subsequently vulcanized, the elastomeric composition is then at least partially brought into contact with water, and afterwards the water is at least partially removed from the elastomeric composition. The elastomeric composition according to the invention can, for example, be used in vehicles and machines as a seal, grommet, disc, coupling or membrane.Type: GrantFiled: May 19, 2017Date of Patent: September 17, 2019Assignee: LEIBNIZ-INSTITUT FUER POLYMERFORSCHUNG DRESDEN E.V.Inventors: Tamil Selvan Natarajan, Amit Das, Klaus Werner Stoeckelhuber, Hai Le Hong, Rene Jurk, Sven Wiessner, Gert Heinrich
