US 2018/0022884 A1 · POLYESTER POLYOL COMPOSITIONS CONTAINING HFO-1336MZZM (Z)

Abstract

Blends, polyol premix compositions, methods of forming such compositions, foamable compositions using the premix compositions, methods of preparing foams containing the premix compositions, and foams made using the premix compositions are described. The polyol premix composition includes a polyester polyol; halogenated olefin blowing agent; and a distribution-enhancing component. In the polyol premix composition, the blowing agent, the polyester polyol, and the distribution-enhancing component form a substantially uniform composition.

Claims20

Dependent claims

A polyol premix composition comprising:

a halogenated olefin blowing agent;
a polyester polyol, and
a distribution enhancing component comprising at least one organic compound having from 1 to 40 carbon atoms, said at least one organic compound being present in the premix in amount effective to enhance the ability of said halogenated blowing agent and said polyol to form a stable, substantially uniform blend that remains as a substantially uniform mixture when stored for a period of four (4) months under ambient conditions.

Dependencies are inferred from the claim text.
