The influence of various powder inorganic fillers (carbon black P 803, P 324 and N 220, silica ZC-120) on the rheometric properties of the rubber compound, physico-mechanical and performance properties of vulcanized rubber based on ethylene propylene diene monomer rubber SKEPT-40, used for rubberizing metal surfaces, was studied. The rubber compound under study based on the above rubber included a vulcanizing agent (sulfur), vulcanization accelerators (2-mercaptobenzthiazole and tetramethylthiuram disulfide), vulcanization activators (zinc white and stearic acid) softener (industrial oil I-8A). It was found that vulcanized rubber with a content of 60.0 parts per hundred parts of rubber (phr) of carbon black N 220 has high physico-mechanical properties, the smallest changes in tensile strength, elongation at break and weight after exposure to aggressive acid-base environments and good frost resistance.
