OIL-AND-PETROL-RESISTANT AND COLD-RESISTANT RUBBER MIXTURE Russian patent published in 2019 - IPC C08L9/02 C08L19/00 C08K3/04 C08K3/06 C08K3/22 C08K5/18 C08K5/40 C08K5/43 C08K5/44

Abstract RU 2688741 C1

FIELD: chemistry.

SUBSTANCE: invention relates to an oil-resistant cold-resistant rubber mixture and can be used in the rubber industry for making oil-and-petrol resistant seals, cuffs for various purposes, hose articles for operation under pressure in hydrocarbon media and at low temperatures. Rubber mixture contains a combination of epichlorohydrin and hydrogenated butadiene-nitrile rubber, ground sulphur, technical carbon N550, technical carbon N220, technical carbon N330, plasticiser - dibutyl sebacate, volcanox 4010 NA/LG, tiuram/tulium volcacite, zinc powder, CZ/EG-C vulcacite, DTDM - dithiodimorpholine.

EFFECT: invention increases frost resistance of the rubber mixture while maintaining oil-and-petrol resistance and elastic strength properties.
