    摘要: Fire extinguishing compositions and methods for extinguishing, controlling, or preventing fires are described wherein the extinguishing agent includes a fluorinated oxirane alone, or in admixture with a co-extinguishing agent selected from hydrofluorocarbons, hydrochlorofluorocarbons, perfluorocarbons, perfluoropolyethers, hydrofluoroethers, hydrofluoropolyethers, chlorofluorocarbons, bromofluorocarbons, bromochlorofluorocarbons, iodofluorocarbons, hydrobromofluorocarbons, fluorinated ketones, hydrobromocarbons, fluorinated olefins, hydrofluoroolefins, fluorinated sulfones, fluorinated vinylethers, and mixtures thereof. Also described are methods of preventing or extinguishing fires by introducing these compositions into an air-containing enclosed area and maintaining the composition in an amount sufficient to suppress combustion of combustible material in that enclosed area.

    摘要: Foamable compositions are provided that include at least one blowing agent, at least one foamable polymer or a precursor composition thereof, and a nucleating agent. The nucleating agent includes a fluorinated oxirane which, in some embodiments, can have up to a maximum of three hydrogen atoms. The fluorinated oxiranes can have a total of from about 2 to about 12 carbon atoms. Also provided is a process for preparing a polymeric foam and a composition that includes a blowing agent and a nucleating agent comprising a fluorinated oxirane.
