Diol Monomers

Based on 835 products - Last update on the Jun 26, 2025

Diols, also known as glycols, are organic compounds which typically appear as colorless, viscous liquids. Functionally, diols are crucial in the production of polyesters and polyurethanes due to their ability to form strong, flexible polymers. Key features include excellent moisture resistance, flexibility, and durability, making them suitable for applications in coatings, adhesives, sealants, and elastomers. 

Alternatives to diols include polyols and other multifunctional alcohols. Sub-types of diols include 1,3-propanediol and 1,4-butanediol.

ETERNACOLL® PH100

by UBE

ETERNACOLL® PH100 by UBE is a solvent-free liquid copolycarbonate diol. Polyurethanes produced from this grade are superior to those based on polyether diol as well as polyester diol and provides flexibility, softness, high chemical resistance as well as high mechanical properties. Also provides enhanced hydrolysis resistance, higher gloss, improved scratch as well as abrasion resistance, better adhesion to metal even after weathering and better corrosion resistance by replacing the blend of a classical polyol by this polycarbonate diol.
