6. A blowing agent consisting essentially of the binary azeotrope-like mixture of claim 1 .
7. A blowing agent consisting essentially of at least about 5% by weight of the binary azeotrope-like mixture of claim 1 .
8. A foamable composition comprising one or more components capable of forming foam and the blowing agent of claim 6 .
9. The foamable composition of claim 8 further comprising one or more additives selected from the group consisting of nucleating agents, flame retardants, colorants, processing aids, cross linking gents, and permeability modifiers.
10. A foam formed from the foamable composition of claim 8 .
11. The foam of claim 10 comprising a thermoplastic foam.
12. The foam of claim 10 comprising a thermoset foam.
13. A closed cell foam comprising the foam of claim 10 .
14. A blowing agent consisting essentially of at least about 15% by weight of the binary azeotrope-like mixture of claim 1 .
