Abstract

The present invention relates to improved internal mould release agents based on particular ammonium or metal salts of phosphoric acid esters, ammonium salts of carboxylic acids and/or ammonium or metal salts of sulfonic acids for producing cellular or compact, optionally glass fibre- and/or natural fibre-reinforced polyurethane mouldings. The polyurethane mouldings produced according to the invention may be laminated or coated with other materials.
