Abstract

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.
