Abstract

The ethylene-propylene-diene rubber (SKEPT-40) was investigated as the main component in the cold-resistant rubber. The optimal vulcanizing system and the ways to improve the cold-resistant indicators by adding the paraffin plasticizer and by combination with polybutadiene (SKD-N) and silicone rubber (SKTFV-803) are developed. The advantages of the investigated rubbers in comparison with the cold-resistant sealing rubber IRP-1375 containing ethylene-propylene rubber are shown. The ways to further improve the cold-resistant performance of rubbers based on ethylene-propylene-diene rubbers are proposed.
