ABSTRACT:
Flame-retardant polyurethane products are produced by mixing and reacting a basic salt-forming compound with an acidic salt-forming compound containing phosphorus and/or halogen compounds in a polyol and/or a polyisocyanate, then reacting the polyol and polyisocyanate.
The flame-retardant polyurethane products may be used for thermal and sound insulation, as a coating agent, as an adhesive, for caulking, for cushioning and for molding useful objects.
