Abstract:
1. An integral foam comprising a foamed polyurethane comprising a foamed polyurethane obtained by mixing a) polyisocyanates; b) relatively high molecular weight compounds comprising groups reactive toward isocyanate groups; c) 15 to 80% by weight, based on the total weight of (a)-(f) of solid particles having an average particle diameter of from 0.01 to 50 μm and being produced by free radical polymerization; d) blowing agents; e) chain extender, crosslinking agent, or mixtures thereof; f) if appropriate, catalyst; and g) if appropriate, other additives to give a reaction mixture and allowing the reaction mixture to react to completion, wherein wherein the total gross density averaged over the core and the edge zone of said foamed polyurethane, according to DIN EN ISO 845, is from 200 to 1000 g/L.
