Abstract RU 2595674 C1

FIELD: rubber industry.

SUBSTANCE: invention relates to rubber industry, in particular to production of rubber mixtures used for production of sealing elements used in production of packer-anchor equipment for oil and gas industry. Mixture contains a combination of hydrogenated butadiene-nitrile rubber and butadiene-nitrile rubber, zinc oxide, technical carbon N 220, technical carbon P 514, oligoester acrylates MGF-9 and TGM-3, herewith it additionally contains polymethylsiloxane liquid-200, "Shinplast" resin, rosil 175, deltagran HVA-2 70 GE, urotropine, resin SF-012A, acetonanil-H, irganox 1010, curing agent - novoperox TBK.

EFFECT: technical result is improvement of properties of conventional tensile strength, tear resistance and hardness, high resistance of the rubber to ageing in aggressive hydrocarbon media at high temperatures.
