Abstract: The present disclosure is directed to refrigerant compositions having reduced flammability profiles. The reduced flammability refrigerants comprise a refrigerant and an additive. Also disclosed are methods of increasing the minimum ignition energy of a refrigerant and methods of increasing the lower flammability limit of a refrigerant. The present disclosure is also directed to a method of scavenging radicals in a refrigerant.

Abstract: Incorporating a cycloaliphatic epoxide such as cyclohexene oxide into a polyol pre-mix containing an amine catalyst and a halogenated hydroolefin blowing agent such as HCFO-1233zd helps to improve the storage-stability of the pre-mix and to ensure that a thermoset foam prepared therefrom is of satisfactory quality.

Abstract: A stable polyol pre-mix composition comprises a blowing agent, a polyol, a surfactant, and a catalyst composition comprising an oxygen-containing amine catalyst and a metallic salt. The oxygen-containing amine catalyst may be, for example, one or more of an alkanol amine, an ether amine, or a morpholine group-containing compound such as, for example, 2-(2-dimethylaminoethoxy)ethanol or N,N,N′-trimethylaminoethyl-ethanolamine. The metallic salt may be, for example, alkali earth carboxylates, alkali carboxylates, and carboxylates of metals selected form the group consisting of zinc (Zn), cobalt (Co), tin (Sn), cerium (Ce), lanthanum (La), aluminum (Al), vanadium (V), manganese (Mn), copper (Cu), nickel (Ni), iron (Fe), titanium (Ti), zirconium (Zr), chromium (Cr), scandium (Sc), calcium (Ca), magnesium (Mg), strontium (Sr), and barium (Ba)

Abstract: A polyol pre-mix composition includes a blowing agent having a halogenated hydroolefin, a polyol, a catalyst composition, and an antioxidant. The antioxidant may be, for example, a benzene diol or a benzene triol or other polyhydroxy-substituted aromatic compound, which is optionally substituted with one or more substituents such as alkyl groups. A two-part system for producing a thermosetting foam blend includes (a) a polyisocyanate and, optionally, one or more isocyanate compatible raw materials; and (b) the polyol pre-mix composition. A method for producing a thermosetting foam blend includes combining: (a) a polyisocyanate; and (b) the polyol pre-mix composition.
