Foam catalyst

WebJul 11, 2016 · Jeffcat S-117 Thisis a formulated strong blowing catalyst for low- and medium-density spray foams. The product is a non-fugitive catalyst because it contains reactive hydroxyl groups which react into the foaming matrix, thus minimizing catalyst odor in finished foams. Jeffcat Z-110 Used in a variety of polyurethane foam applications. WebNov 26, 2008 · Interestingly the foam catalyst was found to be capable of light-off without in situ H 2 reduction unlike the supported nickel catalyst. CH 4 conversion and H 2 and CO selectivity were found to increase as the inlet temperature increased from 650 to 850 °C.
