This paper presents the performance of epichlorohydrin homopolymer (CO), the epichlorohydrin/ethylene oxide copolymer (ECO), and a polypropylene oxide elastomer (PPO) when subjected to various environments at elevated temperatures. Comparisons with other oil-resistant specialty elastomers before and after aging in air and oil are discussed. Low-temperature flexibility, elongation, and other properties are included, as well as permeability evaluations. The data demonstrate the improved performance of polyether elastomers for a service temperature range of -40° to 300°F, especially for under-the-hood applications.
