Such PU-systems preferably further comprise at least one phosphorus-containing compound, most preferably a phosphorus-containing plasticizer, which is preferably halogen-free. The binder on isocyanate basis has preferably an isocyanate content in the range of from 0.01 to 10% by weight referred to the total weight of the system.
