Polymeric mdi prepolymer compositions and flexible foams prepared therefrom |
| abstract |
The present invention relates to prepolymers, comprising (a) a polymethylene polyphenylene polyisocyanate; and (b) a polyether polyol having an average hydroxyl equivalent weight of at least about 700; wherein the resulting prepolymer has an average viscosity of between about 400 to about 2000 centipoise at 25°C. The prepolymer is useful, for example, for the production of polyurethane foams and, more particularly, to medium density flexible foams having superior flow characteristic and fast demold times. |
