<p>Disclosed are light wood-based material products and which comprise: a) from 30 to 92.5% by weight, based on the wood-base material, of wood particles, the wood particles having a mean density of from 0.4 to 0.85 g/cm3; b) from 2.5 to 20% by weight, based on the wood-base material, of polystyrene and/or of styrene copolymer as a filler, the filler having a bulk density of from 10 to 100 kg/m3; and c) from 5 to 50% by weight, based on the wood-base material, of a binder; the mean density of the light wood-base material being less than or equal to 600 kg/m3. Further disclosed is a process for the production of a light wood-base material as defined above wherein said prefoamed polystyrene and/or styrene copolymers, binder and wood particles are mixed and subsequently moulded at elevated temperature and elevated pressure to give said wood-based material. Also disclosed is the use of the light wood-base materials as defined above for the production of pieces of furniture, of packaging materials, in house construction or in interior trim.</p> |
