    Abstract: 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) ≤2,5 Œ d' of the particles (B).

    Abstract: 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.

    Abstract: La presente invención se relaciona con un polímero de estireno expansible que contiene partículas atérmicas y está revestido con un medio de hidrofobización, en donde el medio de hidrofobización contiene 10 a 90% en peso de cuando menos un triéster de por lo menos un ácido graso con un alcohol multihídrico como componente A; 5 a 70% en peso de cuando menos un monoéster de un ácido graso con un alcohol multihídrico como componente B; 5 a 80% en peso de cuando menos una sal de metal de un ácido graso como componente C; 5 a 50% en peso de cuando menos un silicato como componente D; y 0 a 30% en peso de cuando menos un agente antiestático como componente; y la suma de los componentes A a E del medio de hidrofobización totaliza a 100% en peso. La invención también se relaciona con un método para la producción de polímero de estireno expansible revistiendo un polímero de estireno expansible que contiene partículas atérmicas con este medio de hidrofobización, una espuma producida de este polímero de estireno expansible, y el uso de un medio de hidrofobización para revestir polímeros de estireno expansibles que contienen partículas atérmicas.
