    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.
