ABSTRACT:
A synthetic board is prepared by a process of contacting lignocellulosic material with a binder and subsequently forming the treated material into a board by the application of heat and pressure, wherein (a) the binder comprises an organic polyisocyanate and a reactive hydrogen-containing component, especially an aromatic polyester polyol, and (b) the lignocellulosic material is additionally contracted with a surfactant.
