  • Patent number: 10196476
    Abstract: Catalyst compositions useful in the production of insulating polyurethane or polyisocyanurate foam are disclosed. The catalyst compositions impart increased stability of a mixture of the catalyst, a halogen-containing blowing agent, and a polyol.

  • Patent number: 10189963
    Abstract: 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.
