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.
