Abstract: 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/CM³, 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/M³, 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/M³.

Abstract: THE INVENTION RELATES TO A LIGHT MATERIAL CONTAINING WOOD HAVING AN AVERAGE DENSITY IN THE REGION OF BETWEEN 200 TO 600 KG/M³, 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/M³, 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 X D'OF THE PARTICLES (B).
