Light wood-based materials having good mechanical properties and low formaldehyde emission

摘要

A light wood-containing material having an average density in the range from 200 to 600 kg/m, comprising, based in each case on the wood-containing material: A) from 30 to 95% by weight of wood particles; B) from 1 to 15% by weight of a filler having a bulk density in the range from 10 to 100 kg/m, selected from the group consisting of foamable plastic particles and already foamed plastic particles; C) from 3 to 50% by weight of a binder comprising an aminoplast resin and an organic isocyanate having at least two isocyanate groups and, if appropriate, D) additives.
