Abstract

The invention relates to a process for plasticizing wood products for the shaping thereof. According to the process, the product to be treated is impregnated beneath the surface with at least 20 kg of an aqueous solution of maleic acid and glycerol per cubic metre of the wood product and the product is next subjected to a heat treatment at a maximum of 150 degree C. Following plasticization, the wood product can be shaped in a manner which is known per se, for example by bending, and it is then hardened at a temperature of over 150 degree C. The treatment of the wood with a mixture of maleic acid and glycerol facilitates the working of the wood and improves the dimensional stability of the made products.
