Light wood-based materials

摘要

The invention relates to a light material containing wood having an average density in the region of between 200 to 600 kg/m, and which comprises, in relation to the material containing wood, A) 30 to 95% by wt. of wood particles, B) 1 to 25% by wt. of a filling material having a bulk density in the region of between 10 to 150 kg/m, selected from the group consisting of foamable plastic particles and already foamed plastic particles, C) 0.1 to 50% by wt. of a binding agent, and optionally, D) additives. Said claimed material containing wood is characterised by the following relation between the d' values in accordance with the Rosin-Rammler-Sperling-Bennet distribution of the wood particles (A) and the particles of the filling material (B): d' of the particles (A)≤2,5Œd' of the particles (B).
