Polyurethane insulation foam composition comprising a stabilizing compound

A method of making a polyurethane foam product from a polyurethane insulation foam composition comprising:

• reacting the following reactive ingredients of a polyurethane insulation foam composition to form the polyurethane foam product:
• (i) an aromatic isocyanate compound;
• (ii) an isocyanate reactive compound;
• (iii) water;
• (iv) a tertiary amine compound;
• (v) a hydrophilic carboxylic acid selected from a hydroxyl-carboxylic acid, a hydroxyl-polycarboxylic acid, AGS acid and a combination thereof;
• (vi) a halogenated olefin blowing agent;
• (vii) a stabilizing compound wherein the stabilizing compound comprises an un-alkoxylated polyhydroxy compound having 4 or more hydroxyl groups;
• and
• (viii) optionally, other additives;
• wherein Component (v) is present in the polyurethane insulation foam composition in an amount ranging from 0.2 to 4 equivalents of carboxyl group per equivalent of tertiary amines in Component (iv) and Component (vii) is present in an amount of less than 0.8 moles per mole of Component (v);
• wherein a CT REACTIVITY SHIFT of the polyurethane insulation foam composition is less than or equal to 20 and a TFT REACTIVITY SHIFT is less than or equal to 4;
• and wherein the CT REACTIVITY SHIFT and the TFT REACTIVITY SHIFT of the polyurethane insulation foam composition is determined by using Formulas X and Y, respectively:
• CT REACTIVE SHIFT=100*[(CT79−CT0)/CT0] Formula X:
• wherein
• CT79 means a composition's CT as determined using the FOAM REACTIVITY TEST after the composition's B-Side comprising Components (ii) and (iii) has been aged at 40° C. in a closed, pressure-rated, glass container that was placed in an oven for 79 days,
• CT0 means a composition's CT as determined using the FOAM REACTIVITY TEST after the composition's B-Side comprising Components (ii) and (iii) has been aged at 40° C. for 0 days,
• and
• TFT REACTIVE SHIFT=100*[(TFT79−TFT0)/TFT0] Formula Y:
• wherein
• TFT79 means a composition's TFT as determined using the FOAM REACTIVITY TEST after the composition's B-Side comprising Components (ii) and (iii) has been aged at 40° C. in a closed, pressure-rated, glass container that was placed in an oven for 79 days,
• TFT0 means a composition's TFT as determined using the FOAM REACTIVITY TEST after the composition's B-Side comprising Components (ii) and (iii) has been aged at 40° C. for 0 days.
