Polyol - Wikipedia
In organic chemistry, a polyol is an organic compound containing multiple hydroxyl groups (−OH). The term "polyol" can have slightly different meanings depending on whether it is used in food science or polymer chemistry .
Polyol - an overview | ScienceDirect Topics
A polyol is a sugar alcohol containing multiple hydroxyl groups (e.g. glycerol, mannitol, sorbitol and xylitol). From: Tissue Engineering Using Ceramics and Polymers (Second Edition), 2014
Polyol - an overview | ScienceDirect Topics
Polyols 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].

Polyols - What are they, and what are their uses and applications? - Repsol
Polyols are alcohols with more than one hydroxyl group and they constitute one of the main raw materials for manufacturing polyurethane. Polyurethanes are versatile, modern and safe.
Polyols - (Organic Chemistry) - Vocab, Definition, Explanations
Polyols, also known as sugar alcohols, are a class of organic compounds that contain multiple hydroxyl (-OH) groups. They are commonly found in nature and are often used as sweeteners and bulking agents in various food and pharmaceutical products.
Exploring Polyols: Molecular Weights and Applications | In
2023年10月30日 · Polyols, also known as polyhydric alcohols, are a class of organic compounds that contain multiple hydroxyl (-OH) functional groups. These hydroxyl groups make polyols highly reactive and give them unique chemical and physical properties.
What Is Polyol? What Are The Types of Polyol? - Kimpur
2021年12月10日 · 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.
What are the Different Types of Polyols? - Bisley International LLC
2023年9月20日 · Polyols are versatile compounds that serve a multitude of purposes. In this blog, we’ll delve into the two primary types of polyols: polyether and polyester polyols, and explore their unique characteristics and applications. Polyether polyols are formed through the polymerisation of propylene oxide (PO) or ethylene oxide (EO).
