Abstract
The present invention relates to mixtures of 1,1,1,4,4,4-hexafluorobutene (1336mzzm) and 1-chloro-3,3,3-trifluoropropene (1233zd). The blends are useful as blowing agents for polymer foam, solvents, aerosol propellants and heat transfer media.
Claims14
A blowing agent composition comprising:
- from about 30 mole % to about 70 mole % 1,1,1,4,4,4-hexafluorobutene (1336mzzm), wherein said 1336mzzm comprises trans-1,1,1,4,4,4-hexafluorobutene;
- from about 30 mole % to about 70 mole % trans-1-chloro-3,3,3-trifluoropropene (1233zd);
- and
- optionally at least one adjuvant selected from the group consisting of co-blowing agent(s), polyol(s), surfactant(s), polymer modifier(s), colorant(s), dye(s), solubility enhancer(s), flammability suppressant(s), flame retardants(s), antibacterial agent(s), viscosity reduction modifier(s), filler(s), vapor pressure modifier(s), nucleating agent(s), catalyst(s) and combination of any two or more of these.
