Abstract

The article shows the main directions for the development of a formulation for frost-resistant ozone-resistant rubber for sealing purposes. Currently, there are problems with the durability of the operation of parts made of rubber grade NO-68-1 due to the instability of the raw material base of rubbers. A comprehensive analysis of rubbers of various composition and structure was carried out. Based on the results of the analysis, ethylene-propylene, ethylene-propylene diene, and propylene oxide rubbers were selected as the polymer base. Mixtures of various compositions are made from these rubbers. According to the test results, the optimal composition of frost-resistant ozone-resistant rubber was selected.
