Light wood-based materials

摘要

The invention relates to light wood-based materials containing 30 - 92.5 % by wt. of wood particles, in relation to the wood-based material. Said wood particles have an average density of between 0.4 - 0.85 g/cm, 2.5 - 20 % by wt. of polystyrene and/or styrene copolymer as filling material, in relation to the wood-based material. Said filling material has a bulk density of between 10 -100 kg/m, and 5 - 50 % by wt. of binding agents, in relation to wood-based material. The average density of the light wood-based material is less than or equal to 600 kg/m.
