ABSTRACT:
In order to provide a granular material for use as a filler for plastics material and adapted to improve the thermal, mechanical and aesthetic characteristics of the plastics material incorporating it, the wood flour is impregnated with an aqueous solution of melamine resin and dimethyl ketone or methyl-ethyl ketone and, after drying, the mass of wood flour thus impregnated is milled to obtain granules of dimensions suitable for inclusion in the matrix of the plastics material.
