Abstract (en)

[origin: WO2011018372A1] The invention relates to a method for producing a light lignocellulosic material having an average density in the range of 200 to 600 kg/m3, and comprising, on basis of the lignocellulosic material: A) 30 to 95 wt % of lignocellulose particles; B) 1 to 25 wt % of expanded plastic particles having a bulk density in the range of 10 to 100 kg/m3; C) 3 to 50 wt % of a binding agent, selected from the group of aminoplast resin, phenol formaldehyde resin, and organic isocyanate having at least two isocyanate groups; and optionally D) additives are mixed and then pressed under increased temperature and increased pressure, characterized in that the expanded plastic particles are obtained from expandable plastic particles having a content of propellant in the range of 0.01 to 4 wt % relative to the expandable plastic particles.
