The invention relates to flame resistant rigid foams and formulations useful for the production thereof. The polyol formulation must include at least one substance which is inert with respect to isocyanates, does not deplete the ozone layer and has a boiling point below 55&#xb0; C. and a reaction product of at least one compound with an aromatic ring, at least one aldehyde or ketone and at least one primary or secondary amine. This polyol formulation is reacted with an isocyanate, optionally with other commonly used additives, to produce rigid flame resistant foams.

Flame resistant rigid foams and formulations for the production thereof

The invention relates to foam having an apparent density of less than 100 kg/m , in which water is predominantly used as the blowing agent, and to products that contain such foams. The mentioned foams have a large proportion of open cells (>80%).
