Claims
- 1. A formulated polyol composition comprising 1,1,1,2-tetrafluoroethane combined with a polyol composition comprising:
- a) compounds having at least two isocyanate active hydrogens, said compounds having an average hydroxyl number of less than 400 and an average functionality of greater than 4.0;
- b) water; and,
- c) a catalyst;
- wherein the formulated polyol composition is under a pressure sufficient to keep 1,1,1,2-tetrafluoroethane in a liquid state.
- 2. The composition of claim 1, wherein the a) compounds have an average hydroxyl number of 350 or less and a functionality of 4.5 or more.
- 3. The composition of claim 1, wherein the amount of water is 2.5 weight percent or less based on the weight of the polyol composition.
- 4. The composition of claim 1, wherein the amount of 1,1,1,2-tetrafluoroethane is 5 pbw to 15 pbw based on 100 pbw of the polyol composition.
- 5. The composition of claim 1, wherein the viscosity of the formulated polyol composition is 800 cps or less when measured at 78.degree. F. and 80 p.s.i.g., and the amount of 1,1,1,2-tetrafluoroethane is 7 pbw to 13 pbw based on 100 pbw of the polyol composition.
