Publication number: 20120071576Abstract: Polyurethane foam compositions and processes to make flexible polyurethane foams are disclosed. Polyurethane foam is produced in the presence of additives comprising guanidine derivatives. Improvements in physical properties such as air flow, dimensional stability, tensile, tear, elongation and foam hardness is observed when these additives are present in polyurethane formulations. In addition, these additives can minimize polymer degradation under humid ageing conditions resulting in foam products with better mechanical properties.Type: ApplicationFiled: July 8, 2011Publication date: March 22, 2012Applicant: AIR PRODUCTS AND CHEMICALS, INC.Inventors: Juan Jesus Burdeniuc, James Douglas Tobias, Renee Jo Keller, You-Moon Jeon
