    Abstract: Materials which contain lignocellulose, have a core and two covering layers, and contain, in the core, A) 30 to 98 wt. % lignocellulose particles, B) 1 to 25 wt. % expanded plastic particles having a bulk density in the range of 10 to 150 kg/m3, C) 1 to 50 wt. % of one or more binding agents selected from the group consisting of amino resin, phenolic resin and organic isocyanate comprising at least two isocyanate groups, and D) 0 to 10 wt. % additives, and, in the covering layers, E) 70 to 99 wt. % lignocellulose particles, F) 1 to 30 wt. % of one or more binding agents selected from the group consisting of amino resin, phenol formaldehyde resin and organic isocyanate comprising at least two isocyanate groups, and G) 0 to 10 wt. % additives. The lignocellulose particles of the covering layers E contain at least 25 wt. % lignocellulose-containing chips, and the expanded plastic particles B are non-homogeneously distributed in the core.

    Abstract: The disclosure relates to lignocellulosic materials having a core and two outer layers, comprising in the core A) 30% to 98% by weight of lignocellulose particles; B) 1 % to 25% by weight of expanded plastics particles having a bulk density in the range from 10 to 150 kg/m3, C) 1 % to 50% by weight of one or more binders selected from the group consisting of aminoplast resin, phenoplast resin, and organic isocyanate having at least two isocyanate groups, and D) 0% to 10% by weight of additives 15 and in the outer layers E) 70% to 99% by weight of lignocellulose particles, F) 1 % to 30% by weight of one or more binders selected from the group consisting of aminoplast resin, phenol-formaldehyde resin, and organic isocyanate having at least two isocyanate groups, and G) 0% to 10% by weight of additives, where the lignocellulose particles of the outer layers E comprise at least 25% by weight of lignocellulosic chips and the expanded plastics particles B are present in non uniform distribution in the core and the expanded plastics particles B are present in nonuniform distribution in the core, therefore the weight ratio X of expanded plastics particles B to lignocellulose particles A in the outer regions of the core (“exterior”) is different from the weight ratio Y of expanded plastic particles B to lignocellulose particles A in the inner region of the core (”interior”).
