A catalyst and process are provided for producing polyurethanes by contacting an organic polyol and an organic isocyanate with a catalyst comprising an N-substituted alkoxyalkyl piperazine and preferably additionally comprising an N-alkoxyalkyl morpholine wherein the alkylene moieties of the morpholine and piperazine are independently selected from the group consisting of C.sub.1 to about C.sub.5 alkylene moieties, and wherein the alkoxy moieties are independently selected from the group consisting of C.sub.1 to about C.sub.3 alkoxy moieties.

Catalyst system and process for the production of polyurethanes

A catalyst system and process are provided for producing polyurethane foams using a carboxylic acid blowing agent, wherein an organic polyol and an organic polyisocyanate are contacted with a catalyst system comprising a dialkylcyclohexylamine and an N-substituted alkoxyalkyl piperazine.

Catalyst system for use in producing carboxylic acid blown polyurethane

Polyurethane foams with excellent physical properties are obtained by using a catalyst composition of a tertiary amine and 2-ethylhexanoic acid.

Catalyst for making polyurethanes

Disclosed is a synergistic catalytic combination of 1,2-dimethylimidazole with tris(3-dimethylaminopropyl)amine and a salt of 1,8-diazabicyclo(5,4,0)undecene-7. The combination catalyst is useful in polyurethane systems such as elastomers, microcellular, rigid, semirigid, and flexible foams, such as integral skin semiflexible foams used in the manufacture of steering wheels.

Catalyst blend containing 1,2-dimethylimidazole

Polyurethane foams with excellent physical properties can be obtained by using a partial salt between N,N-dimethylaminopropane-1,3-diamine (DMAPA) and a branched octanoic acid.
