Polyurethane foam odor related to Volatile Organic Compounds (VOCs) emissions has emerged globally as a major issue during recent years. Many contributing volatile components have been identified and significant progress has been made within the industry towards reducing their content in foam. One major family of contributors, which have received significant attention, is amine catalyst additives. Some of these are volatile and therefore contribute to the VOC. To date, efforts to replace highly volatile amines with more acceptable molecules such as so-called reactive catalysts have resulted in compromises in foam processing, properties and formulating cost, or a combination of these. The latest development of a range of catalytically active polyols has successfully provided an attractive alternative route to the elimination of the volatile amine catalysts without major compromise. This report will provide the reader with details of this development and how it can be applied to the reduction and, in many cases, the elimination of volatile amines in slabstock foam. New data will be presented to demonstrate how these polyols can be applied by the industry effectively to reduce VOC emissions in flexible slabstock foams.
