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).
Claims10
A blowing agent composition comprising at least about 5% by weight of vinylidene fluoride (CH2═CF2) and from about 0.1 to about 60% by weight of at least one co-blowing agent.
A foam premix composition comprising polyol and vinylidene fluoride (CH2═CF2).
A method of forming a foam comprising adding to a foamable and/or foaming composition a blowing agent comprising vinylidene fluoride (CH2═CF2) under conditions effective to form a foamed cellular structure, wherein said foamable or foaming composition comprises a foam-forming substance selected from isocyanate, polyol and combinations of these.
