ALDEHYDE SCAVENGERS MIXTURES FOR POLYURETHANE FOAMS

摘要

A polyurethane composition comprising a mixture comprising at least two aldehyde scavengers, a polyurethane product, and a process for making polyurethane foam are disclosed. The mixture of 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, and aminosiloxane.
