Effect of Isocyanate and Polyol Mixing Speed on The Microstructure andProperties of ۲k Polyurethane Foam

This study investigates the impact of isocyanate and polyol mixing speed on the microstructure andproperties of polyurethane foam, with a specific focus on cell diameter and density, foam density,and durability. Our experimental analysis reveals that higher mixing speeds result in smaller and moreuniform cell sizes, while lower mixing speed produce larger and more irregular cells. These changesin cell structure directly correlate with foam density and other critical properties, like durability.Foams produced at higher mixing speeds exhibit increased density and enhanced durability, makingthem suitable for applications requiring robust performance. The findings of this study providevaluable insights into optimizing the mixing process to tailor the properties of polyurethane foamsfor specific industrial applications
