This invention relates to a process for preparing viscoelastic polyurethane foam in which the isocyanate-reactive component comprises a specific polyol blend, and to viscoelastic polyurethane foam wherein the isocyanate-reactive comprises the specific polyol blend. The polyol blend may be an in situ formed polyol blend.

Blends, polyol premix compositions, methods of forming such compositions, foamable compositions using the premix compositions, methods of preparing foams containing the premix compositions, and foams made using the premix compositions are described. The polyol premix composition includes a polyester polyol; halogenated olefin blowing agent; and a distribution-enhancing component. In the polyol premix composition, the blowing agent, the polyester polyol, and the distribution-enhancing component form a substantially uniform composition.

Embodiments of the present disclosure are directed towards semi-flexible foam formulations that can be utilized to form semi-flexible foams. As an example, a semiflexible foam formulation can include a first polyether polyol having an average nominal hydroxyl functionality from 2 to 4 and a number average equivalent weight from 120 to 1500, a second polyether polyol having a having an average nominal hydroxyl functionality from 4 to 8 and a number average equivalent weight from 120 to 800, and a third polyether polyol having an average nominal hydroxyl functionality from 2 to 4 a number average equivalent weight from 200 to 500 and toluene diisocyanate.
