Abstract: The production of fireproof rigid polyurethane foam by reacting polyisocyanates with polyols in presence of water and/or other blowing agents involves adding flour and/or starch in combination with acid-forming fire retardant(s) to the reaction mixture, the flour/starch being used in a pumpable form obtained by mixing with a liquid fire retardant and/or polyol. Independent claims are also included for (1) a method for the production of starch suspensions in a form which can be metered by pumping for use in fireproof rigid polyurethane foam, by mixing flour and/or starch with a liquid fire retardant and/or a polyol (2) fireproof rigid polyurethane foam obtained by this method.

Abstract: Emulsions containing polyether alcohols are used in the production of hard foams based on isocyanates to improve the temperature stability of the foams. Storage-stable halogen-free emulsions used in the production of hard foams based on isocyanates contain: (a) compounds containing hydrogen atoms reactive towards isocyanate groups; (b) water; (c) halogen-free propellants; and optionally (d) usual auxiliary aids and/or additives. (a) is used in an amount of 0.2-80 wt.% and has a functionality of more than 1.5, and an OH number of 10-100 mg KOH/g. (c) consists of 3-10 C hydrocarbons. Independent claims are also included for: (1) the production of the hard foams described; (2) the foams, and (3) the use of the polyether alcohols described.
