Acclaim® polyether Acclaim® polyol is a polyether polyol based on propylene oxide. This high-performance, low-monol polyether is prepared with Bayer’s proprietary IMPACT® technology, using a patented organo-metallic propoxylation catalyst. Acclaim polyol is used in polyurethane and other applications, including cast elastomers, adhesives and sealants, epoxy flexibilizers, defoamers, lubricants, crude oil de-emulsifiers and plasticizers. Acclaim polyol contains extremely low levels of monol. In some polyurethane systems, formulation changes, such as reducing the cross-linking level or changing the hard-segment content, may be necessary to maximize the benefits of using Acclaim polyols.
