Abstract:
The invention described herein generally pertains to a composition and a method for improving the shelf life of a gaseous hydrofluoroolefin propellant, the improvement comprising at least the increased aromatic polyester polyol(s) in combination with a tertiary amine catalyst comprising at least two cyclohexyl rings and an aliphatic metal salt catalyst, the amine catalyst having less than 10% nitrogen on a weight basis.

Claim (Index 18):
A two-component polyurethane foam comprising a reaction product of:\n an \u201cA-side\u201d diisocyanate with an HFO-1234ze propellant; and a \u201cB-side\u201d blend with an HFO-1234ze propellant; the polyurethane foam reaction product comprising:\n at least one aromatic polyester polyol and no more than approximately 10 wt. % aliphatic polyether polyol, \n the at least one aromatic polyester polyol selected from the group having the following repeating formula: \n having a viscosity at 77\u00b0 F. (25\u00b0 C.), of between approximately 2,000-4,500 cP; and wherein n is sufficient repeat units to achieve the viscosity; and having a viscosity at 77\u00b0 F. (25\u00b0 C.) of between approximately 2,500-3,500 cP; and n being a value sufficient to achieve the viscosity; at least two catalysts comprising:\n at least one tertiary amine catalyst comprising at least two cyclohexyl rings; \n at least one aliphatic metal salt catalyst; and \n up to about 1.5 wt. % water.
