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® PH50

by UBE

ETERNACOLL® PH50 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 to the final polymer. Also provides excellent hydrolytic stability, high thermal stability, enhanced scratch resistance, hardness, abrasion resistance and shear resistance.

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.

ETERNATHANE®

by UBE

ETERNATHANE® by UBE is a series of polycarbonate-based and isocyanate-terminated urethane prepolymer with customizable polycarbonate and isocyanate composition, for polyurethane applications requesting high performance and maximized durability in harsh conditions overtime. This prepolymer series can be supplied in a wide range of free NCO content, allowing to meet your specifications and polyurethane properties. This series present a working pot life useful for both machine and hand-batching procedures. ETERNATHANE®-based polyurethanes properties can be adjusted by using a standard or a mixture of different curative agents, such as UBE ETERNACOLL® polycarbonate diol. Polyurethanes based on ETERNATHANE® exhibit enhanced durability against extreme conditions and maintaining original performance overtime.
