Long-Term Serviceability of Elastomers in Modern Engine Coolants

Source

The aging of elastomers in engine coolants after extended periods of service can be both a physical process (stress/strain relaxation) and/or a chemical change. Engine coolants are essentially aqueous and non-aqueous electrolytes coupled with inorganic inhibitor systems, as well as new organic acid systems. The long-term effects of this environment are reviewed. Chemical and functional tests are utilized to model these aging processes. This review will offer a better understanding of the long-term suitability of typical candidate elastomers.
