Disclosed are polyurethane foam compositions and methods for making flexible polyurethane foams. The polyurethane foam is produced in the presence of an additive containing a guanidine derivative. When these additives are present in the polyurethane formulation, improvements in physical properties such as airflow, dimensional stability, tension, tearing, elongation and foam hardness are also observed. In addition, these additives can minimize polymer degradation under moisture aging conditions and can result in foam products with better mechanical properties. |
