WEBPolyols are compounds possessing two or more hydroxyl functional groups that are available for organic reactions with isocyanates to produce PU [52]. In other words, Polyol is responsible for providing long flexible segments, to build elastic polymers [53].
What Is Polyol? What Are The Types of Polyol? - Kimpur
WEBDec 10, 2021 · Polyol compounds are characterized based on their hydroxyl numbers (OH, mgKOH/g). The hydroxyl numbers decrease depending on the increase in the molecular weights of the polyols. Polios are primarily separated as two groups: polyethers and polyesters. 80-90% of the polyols used today are polyether polyols.
