Described herein is a process for producing polyurethane foams having a density of 30 g/dmto 70 g/dm, in which (a) aromatic polyisocyanate is mixed with (b) polymeric compounds having isocyanate-reactive groups, (c) optionally chain extender and/or crosslinking agent, (d) catalyst, (e) blowing agent including water, (f) 0.1% to 5% by weight of lactam, and (g) optionally additives, at an isocyanate index of 50 to 95 to form a reaction mixture, and the reaction mixture is converted to the polyurethane foam, wherein the catalyst includes metal catalyst and amine catalyst, and the amine catalyst has tertiary nitrogen atoms and the content of tertiary nitrogen atoms in the amine catalyst is from 0.0001 to 0.003 mol/100 g of foam. Also described herein is a polyurethane foam and a method of using such a flexible polyurethane foam for the production of cushions, seat cushions, or mattresses.

Polyurethane foams with reduced aromatic amine content

The invention relates to thermoplastic polyurethanes (hereinafter TPUs) suitable for the production of optical conductors, to a process for their production, and also to optical conductors based on TPUs.

Light guides made of thermoplastic polyurethanes

Dispersion comprising functionalized metal oxide particles, polymerizable compounds and if appropriate a solvent and their use for stabilizing polymers.

Dispersions comprising functionalized oxidic nanoparticles

The present invention relates to cellular polyisocyanate polyaddition products whose density to DIN EN ISO 845 is from 200 to 800 kg/m, and also to prepolymer composed of at least one diisocyanate (a) and of at least one polyether alcohol (b), where the at least one polyether alcohol (b) comprises the following components:

Cellular elastomer with little tendency toward creep at high temperatures

Thermoplastic polyurethane (i) comprising from 20% by weight to 70% by weight of isocyanate dissolved in the thermoplastic polyurethane, based on the total weight of the thermoplastic polyurethane (i) comprising the isocyanates.

Isocyanate-containing thermoplastic polyurethane

The invention relates to a cellular elastomer which is anisotropic, with anisotropy being defined by the compressive modulus in one of three orthogonal directions being greater than that in the other two directions by a factor of at least 1.5. The invention also relates to a cellular elastomer containing magnetizable particles which have a chain-like alignment along one spatial direction. The invention also relates to a process for producing a cellular elastomer containing magnetiable particles and the use of such elastomers in articles of manufacture.
