Abstract:
This invention relates to compositions and methods which make advantageous use of vinylidene fluoride (CH2═CF2), and in particular embodiments, to heat transfer fluids and heat transfer methods, blowing agents, and thermoplastic foams which utilize vinylidene fluoride (CH2═CF2). Compositions of the present invention include from about 0.1 to about 60 percent, on a weight basis, of a co-agent and from about 99.0 to about 40 percent, on a weight basis, of vinylidene fluoride (CH2═CF2).
Abstract:
In certain non-limiting, aspects, the present invention relates to storage stable premixes of a polyol suitable for polyurethane or polyisocyanurate foam preparation having, at least, 1,1,1,4,4,4-hexafluoro-2-butene (1336mzzm) as the blowing agent and optional one or more additional additives and/or auxiliary blowing agents in amounts suitable for polyurethane or polyisocyanurate foam preparation.

Abstract:
The present invention relates to polyurethane foams having a polymeric foam structure including a plurality of closed cells therein; and an HFO or HCFO blowing agent, including HCFO-1233zd. In certain aspects, the present invention relates to foam premixes, and the resulting foam structures, that include HCFO-1233zd as blowing agent used alone, or in certain aspects, in a blend with a co-blowing agent such as cyclopentane, iso-pentane, n-pentane, or methyl formate.
