Abstract

The properties of elastomers based on a combination of acrylonitrile-butadiene (NBR), ethylene-propylene (EPDM) rubbers and chlorosulfinated polyethylene (CSM) have been studied for the first time, which have been vulcanized by sulfur-free effective systems. The best balance in terms of frost resistance, heat resistance and fuel resistance is demonstrated by rubbers whose formulations are generally dominated by polar CSM and NBR with lower EPDM content (10-20 mas.h). The results of six-month field tests in tropical climate conditions demonstrate high resistance of elastomers to microorganisms. The obtained results stipulate the prospects of application of the created rubbers for operation in different climatic zones.
