ABSTRACT:
The present invention is related to polyurethane/polyisocyanurate foams containing a mixture of aliphatic dibasic esters, comprising varying amounts of the dimethyl esters of adipic, glutaric, and succinic acids. The foams of the present invention exhibit reduced smoke generating characteristics when compared to the same foam without the dibasic esters.
