Abstract: CELLULAR, MOLDED POLYURETHANE PARTS, PROCESS FOR THEIR PREPARATION BY THERMOFORMING OF POLYESTER-URETHANE FOAM AND THEIR USE A cellular polyurethane having a density of from 15 Kg/m3 to 400 Kg/m3 obtained by means of thermoforming, in a forming tool, at a compression factor of from 1 to 10 and temperatures of from 140.degree.C to 200.degree.C, polyester-urethane foams having a density of from 15 Kg/m3 to 40 Kg/m3 which are based on aromatic polyisocyanates and polyester polyols. The resulting polyurethane shaped objects are suitable for use as self-supporting trim panels, headliners, engine compartment covers, or instrument panels in the automotive, aircraft or railway industries.

Abstract: O.Z. 0050/032961 of the disclosure: A process for the manufacture of dimensionally stable polyurethane foams by releasing, and curing by interaction with the atmosphere, a mixture, which is under pressure, of prepolymers, containing isocyanate groups, and blowing agents, with or without assistants and additives, wherein the prepolymers, containing isocyanate groups, are obtained by reaction of organic polyisocyanates with difunctional to octafunctional polyester-polyols and/or. polyether-polyols, containing chemically bonded tertiary amino groups in the polymer chain, or, preferably, with mixtures of such polyester-polyols and/or polyether-polyols and nitrogen-free polyester-polyols and/or polyether-polyols.

Abstract: To prepare light-stable polyurethane integral skin foams, especially soft integral foams, aliphatic and/or cycloaliphatic polyisocyanates, both categories preferably containing urethane groups and/or biuret groups, are reacted with polyols in the presence of blowing agents and of a synergistic catalyst combination comprising an alkali metal hydroxide, alkali metal alcoholate, alkali metal phenolate, alkali metal salt of a weak acid and/or hexahydrotriazine derivative and an organic tin, zinc and/or iron(II) compound, in the presence or absence of assistants and adjuvants. The preferred catalyst combination is tri-(dimethylaminopropyl)-s-hexahydrotriazine and dibutyl-tin dilaurate.

Abstract: The method is effected by the reaction between a modified organic polyisocyanate and at least two reactive hydrogen atoms and optionally with elongators of the chain, in the presence of pore formation agents, catalysts and optionally by standard auxiliary means and/or additives, in a closed press mould in compaction. By the method at least one modified organic polyisocyanate of pure MDI and at least one polyetheralcohol (polyoxyalkylenepolyol) with NCO content less than 15 at. % react together. 6 claims
