Patent Description:
Foams are dispersions in which a gas is dispersed in a liquid material, a solid material, or a gel material. Foams can be formed by a chemical reaction of polyols and isocyanate. Foams can be utilized for a number of various applications, including insulation, bedding, furniture, vehicle seating, and carpet backing, among others. <CIT> relates to a polyurethane foam stabilizing additive that comprises from about <NUM> to about <NUM> weight percent a hydrocarbon oil, and in from about <NUM> to about <NUM> weight percent a polyester polyol which is a solid at room temperature.

Formulated polyol compositions including a sucrose propoxylated polyol, a polyether triol, and a propoxylated homopolymer triol and flame retardant consisting of triethyl phosphate and tris(<NUM>-chloroisopropyl)-phosphate are disclosed herein. Advantageously, the formulated polyol compositions disclosed herein can provide an improved phase stability as compared to other compositions. The improved phase stability can be shown by a lack of phase separation over particular time intervals. In other words, the formulated polyol compositions do not phase separate over particular time intervals, i.e. the formulated polyol compositions are maintained as a single phase over particular time intervals. Improved phase stability can be advantageous for a number of applications, including A-side B-side type polyurethane applications. For A-side B-side type polyurethane applications, a polyol composition is withdrawn from a container, e.g., the B-side, to be mixed with an isocyanate, e.g., the A-side, for foam formation. Utilizing a phase stable polyol composition can help provide that a more uniform mixture of the A-side and the B-side are supplied for the foam formation. Advantageously, utilizing a more uniform mixture of the A-side and the B-side for the foam formation can help reduce undesirable foam defects that may result from ununiform supplies of the A-side and the B-side. Further, the formulated polyol compositions disclosed herein can be cured to provide foam products having one or more properties desirable for a number of applications, such as acoustic insulation and/or thermal insulation, among others.
