ABSTRACT:
A method for producing a synthetic board from cellulosic and/or lignocellulosic materials wherein a polyisocyanate binder is applied to the hot and wet fibrous material in the blow line out of the refiner of the board forming process. Polyphenylpolyisocyanates, such as a mixture of diphenylmethane-4,4'-diisocyanate and polymethylene polyphenyl polyisocyanates, are a particularly suitable binder.
