Abstract: It was shown that contact of rubbers with oil causes sequential penetration of hydrocarbons having different composition into the elastomer material (quick diffusion of light hydrocarbons takes place during the first day, longer process of penetration of heavier hydrocarbons) and extraction of a plasticizer, which spoils low-temperature characteristics. Modelling of diffusion processes at room temperature was carried out; coefficients of diffusion were determined and technological approaches, which allow reducing wash-out rate of plasticizers were suggested.
