Abstract
Polyurethane foams are very versatile materials applied in different branches of industry. Their popularity is attributed, among others, to the flexibility in engineering their mechanical performance by the adjustment of their formulations. One of the most crucial factors is the isocyanate index, determining the ratio between the free hydroxyl and isocyanate groups present in the polyurethane system. By the change of this ratio, the mechanical properties of foams may be adjusted. In the presented paper, we presented the isocyanate index's influence during foams’ preparation on their thermomechanical performance analyzed by the dynamic mechanical analysis.
