Abstract

Journal of Cellular Plastics, Ahead of Print.
Poly (urethane-urea) foam (PUU Foam) from an amine-based polyether polyol (APP) is different from Sucrose-Sorbitol based polyether polyol (SSPP). In this study, rigid PUU Foams produced from an amine-based polyol, (Amine value: 100 mg KOH/g, Hydroxyl ...
