Abstract

Polyurethane floor covering products are formed from a web layer containing at least 30% by weight fibers. A cooled polyurethane foam formulation which includes at least one polyisocyanate, water and at least one polyol having an equivalent weight of at least 500 is applied to the web layer. The wetted web layer is then compressed to mechanically wet out the fibers, gauged and heated to cure the foam formulation.
