Abstract:
A one-component foam formulation contains a pre-polymer and a blowing agent, the pre-polymer being the reaction product of a polymeric polyol component having an average hydroxyl functionality in a range of 2.3 to 2.85 hydroxyl functionalities per molecule as determined using ASTM D4274-11 (method D); and where the polymeric polyol component has an effective average molecular weight in a range of 4500 and 10000 grams per mole, one or more than one type of chain extender molecule having 3 to 6 carbon atoms and 2 to 4 reactive functionalities selected from a group consisting of hydroxyl and amine functionalities per molecule, a polyisocyanate having a functionality in a range of 2.1 to 3.0 —NCO functionalities per molecule as determined by ASTM D7252-06(2011)e1; and a catalyst.

Claim (Index 1):
A one-component foam formulation comprising a prepolymer, a blowing agent and, optionally, additional additives wherein the prepolymer is a reaction product of prepolymer reactants comprising:\n a. a polymeric polyol component that comprises a blend of diols and triols, the polymeric polyol component having an average hydroxyl functionality in a range of 2.3 to 2.85 hydroxyl functionalities per molecule as determined using ASTM D4274-11 (method D); and where the polymeric polyol component has an effective average molecular weight  M  in a range of 4,500 to 10,000 grams per mole as calculated according to equation (2):\n M =\u03a3 i=1 n w i M i /\u03a3 i=1 n w i \u2003\u2003(2) \n b. one or more than one type of chain extender molecule having 3 to 6 carbon atoms and 2 to 4 reactive functionalities selected from a group consisting of hydroxyl and amine functionalities per molecule; c. a polyisocyanate with a functionality in a range of 2.1 to 3.0 \u2014NCO functionalities per molecule as determined by ASTM D7252-06(2011)e1; and d. a catalyst; where the one-component foam formulation is free of toluene diisocyanate and reaction products of toluene diisocyanate and wherein the polymeric polyol component (a) provides 40-85 mole-percent of the reactive functionalities relative to total hydroxyl and amine functionalities provided by the polymeric polyol component (a) and the chain extender molecule (b) and wherein the polyisocyanate is present at a concentration relative to polyol and chain extender molecule such that there is an average of 12-20 weight-percent unreacted \u2014NCO functional groups based on the total weight of isocyanate and polyol in the formulation as determined by ASTM D2572-97(2010).
