Beschreibung
Zusammenfassung:	A polyurethane composition comprising an aldehyde scavenger, a polyurethane product, and a process for making polyurethane foam are disclosed. The scavenger compounds can reduce, if not eliminate, the emissions of aldehydes from polyurethane foams. The scavenger compounds comprise at least one member selected from the group consisting of: phenol or substituted phenol, a 1, 3-dicarbonyl compound, a polyamine bearing a 1, 3-propanediamino function, melamine, a 1, 2-diaminocycloalkane, an ammonium salt; a compound containing the bisulfite anion, titanium dioxide and aminosiloxane. L'invention concerne une composition de polyuréthane comprenant un entraîneur d'aldéhydes, un produit de polyuréthane; et un procédé de fabrication de mousse de polyuréthane. Les composés entraîneurs peuvent réduire, voire éliminer les émissions d'aldéhydes des mousses de polyuréthane. Les composés entraîneurs comprennent: au moins un élément choisi dans le groupe constitué par: phénol ou phénol substitué, un composé 1,3-dicarbonyle, une polyamine à fonction 1,3-propanediamino, de la mélamine, un 1,2-diaminocycloalcane, un sel d'ammonium; un composé contenant l'anion de bisulfite, du dioxyde de titane et un aminosiloxane.
