Abstract

The possibility of using ethylene-propylene-diene (SKEPT-40) and methylphenylsiloxane (SKTFV-803) rubbers in the formulation of cold-resistant and ozone-resistant rubber was investigated. The optimal ratio of rubber in the rubber mixture, mixing method and vulcanizing system are proposed. The elastic-strength and thermo cold-resistant characteristics of vulcanizates were determined. It is shown that the investigated rubber based on EPDM and SKTFV has improved physicomechanical and cold-resistant indicators compared to the sealing rubber IRP-1375 based on a mixture of ethylene-propylene and butadiene-styrene rubbers.
