The present invention is directed to a polyol blend comprising a polyether polyol having at least two and no more than three hydroxyl groups and from about 5 to about 40 percent by weight based on the total weight of the two components of a dispersion of a polyurea and/or polyhydrazodicarbonamide in an organic compound containing at least one hydroxyl group, the solids content of said blend being from about 1 to about 8 percent by weight. The polyol blend is useful in the production of polyurethane products.

Novel system for the production of polyurethanes

The present invention is directed to a blend of a polyether polyol and a polymer polyol, the blend having a solids content of from about 2 to about 15 percent by weight and the use of such blends in manufacturing polyurethane products.

The instant invention is directed to a process for heat sealing flexible polyurethane foam, comprising:

Process for heat sealing polyurethane foam

The instant invention is directed to a polyol having a molecular weight of 2,000 to 8,000 which is especially suited for use in the production of heat sealable foams, comprising the adduct obtained by sequentially reacting:

Polyols derived from 4,4,4-trichloro-1,2-epoxybutane and/or

The instant invention is directed to the post treatment of flexible polyurethane foams. It has been found that the water absorbency and penetration of flexible polyurethane foams can be enhanced by washing and/or impregnating the foam with an aqueous solution of specified organic siloxane surfactants and allowing the treated foam to dry.
