PETOL 36-3BR is a high reactivity capped triol, nominal 4700 molecular weight, designed for cold- cure flexible molded foams and semi-rigid foams. PETOL 36-3BR has a high content of primary hydroxyl groups and is normally used in TDI/MDI or MDI blend formulations. Because of high Eo content, the product may render opalescent, at temperatures below 30° C.
