ABSTRACT
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 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.
