[0002] Polyurethane foams are widely used in construction, transportation, and electronics applications. However, such polyurethane foams often include specific properties that make them prone to specific safety problems. For example, such polyurethane foams generally have their inherent chemical properties (i.e., the “-NH-COO- groups” of the polyurethane foam cause a lower decomposition temperature than many other polymers) and physical properties (i.e., the low density of the polyurethane causes intense dripping during combustion, and the porous structure promotes oxygen and heat transfer), which tend to cause rapid fire growth. Therefore, a polyurethane foam formulation having improved safety properties is desired.
