A comparative analysis of the physical-mechanical, low-temperature properties, and thermal aging resistance of vulcanizates based on domestic (SKEPT-50) and foreign (Keltan 4450) ethylene propylene diene rubbers was conducted. It was revealed that samples based on SKEPT-50 have a higher range of physical-mechanical properties compared to samples based on Keltan 4450. In terms of low-temperature characteristics, both vulcanizates meet the requirements for rubber intended for exploitation in regions with cold climates.
