ABSTRACT
DMAMP-80, dimethylaimnomethylpropanol (DMAMP-80 is a trademark of ANGUS Chemical) is an amino-alcohol with a structure similar to that of DMEA (N, N- Dimethylethanolamine) indicating its potential as an alternative to this compound. Compared to DMEA, DMAMP-80 is a catalyst with lower volatility and is not a lachrymator.
When evaluated in four representative foam technologies (flexible slabstock, HR molding, NVH and semi-rigid packaging foams) DMAMP-80 was shown to be a viable alternative to DMEA. Foams produced with DMAMP-80 had properties that were similar to those made with DMEA, but without odor at demold, as were the DMEA foams. No PVC staining of NVH foam by DMAMP-80 was observed.
Overall, DMAMP-80 appears to be a viable alternative to DMEA as an amine catalyst for polyurethane foams.
