FIELD: chemistry.
SUBSTANCE: invention relates to rubber industry. Described is a rubber mixture for the production of frost-resistant rubber products used in automotive industry, electrical engineering and production of construction materials, based on ethylene-propylene-diene rubber grade “СКЭПТ-40” or “СКЭПТ-50” and powdered “СВМПЭ”, including sulphur, thiuram, zinc oxide, stearic acid, technical carbon N330, with the following ratio of initial components, wt.pts.: “СКЭПТ-40” or “СКЭПТ-50” 100.0; “СВМПЭ” 10.0; technical carbon of N330 grade 50.0; zinc oxide 5.0; stearic acid 1.0; thiuram 1.5; sulphur 2.0.
EFFECT: obtaining rubber with high frost resistance and resistance to thermal aging in the medium of air and brake fluid.
