Beschreibung
Zusammenfassung:	The invention relates to microcellular polyurethane elastomers which can be produced by reacting polyisocyanates with compounds having at least two hydrogen atoms which are reactive with isocyanate groups. Said elastomers are characterised in that they contains a combination a) made of ai) an aromatic phosphite having a phosphorus content of between 9,00 - 11,00 wt.- %, and aii) an amine compound. The molar ratio between ai) and aii) is between 0,005 - 4,0.
