Shaped PU foam articles, preferably mattresses and/or cushions, wherein the polyurethane foam has been obtained by reaction of at least one polyol component and at least one isocyanate component in the presence of at least one compound of formula (1a) and at least one compound of formula (1b) and at least one blowing agent, are described.

Shaped PU foam articles

A catalyst composition for making polyurethane foam, the catalyst composition including a compound having a general formula RRRN, wherein each of R, Rand Rare independently selected from the group consisting of: wherein n=1 to 5; and R4, R5 and R6 are each independently hydrogen, methyl, ethyl and propyl groups; hydrogen, a C1-C6 alkyl group compound, a C1-C6 cycloalkyl group compound, a C1-C6 alkenyl group compound, a C1-C6 alkynyl group compound, a C1-C6 aryl group compound, and a C1-C6 aralkyl group compound, each group being substituted or unsubstituted; wherein at least one of R, Rand Ris a compound according to formula (I). A polyurethane composition and method for forming a polyurethane foam are also disclosed.

Amine composition useful for making polyurethane foam

A composition and method for producing a tertiary amine is disclosed. The tertiary amine is contacted with an inert gas. The inert gas is nitrogen or more preferably argon. The amine composition is useful in producing polyurethane foam with lower levels of chemical emissions particularly lower emissions of toxic chemicals.

Tertiary amine composition and method for making the composition

A polyurethane catalyst composition comprises N,N'-bis(3-dimethylaminopropyl) urea and 3-dimethylaminopropyl urea in a ratio that can be varied to systematically control flowability, % open cell content and k-factor value for rigid polyurethane foam to enhance processibility. Increasing the N,N'-bis(3-dimethylaminopropyl) urea to 3-dimethylaminopropyl urea ratio decreases the open cell content and k-factor value of the foam whereas decreasing the N,'N-bis(3-dimethylaminopropyl) urea to 3-dimethylaminopropyl urea ratio improves the flowability of the foaming composition.
