TRiiSO distributes a wide range of standard glycol adipate  polyols that allow formulators to produce high quality polyurethanes.  Polyols contain reactive hydroxyl (OH) groups which react with isocyanate (NCO) groups on isocyanates to form polyurethanes. 

Standard glycol adipate -based polyurethanes provide enhanced UV resistance, excellent resistance to oils and fuels, and better abrasion resistance and tensile and tear strength compared to polyether-based polyurethanes.  However, polyester-based polyurethanes are more susceptible to hydrolysis and provide poor resistance to weak acids and bases compared to polyether-based polyurethanes.

Standard glycol adipate polyols are  formed by the condensation reaction of a glycol with a dicarboxylic acid.  The nature of this reaction results in a relatively high polydispersity (broad molecular weight distribution).

There are several key characteristics which define what performance properties a given glycol adipate polyol will impart in a given polyurethane.  These characteristics include:  the hydroxyl number or hydroxyl value  (OH value), OH equivalent weight, molecular weight, and the functionality of the glycol adipate polyol.

Hydroxyl number (OH ) is the measure of the hydroxyl group content of gram of polyol.  Hydroxyl value is measured by titrating a known mass of glycol adipate polyol against potassium hydroxide (KOH), and is expressed as mg KOH/g.  Lower hydroxyl values indicate lower hydroxyl content and a higher molecular weight for the overall glycol adipate polyol.


Molecular Weight is determined by multiplying the equivalent weight by the glycol adipate polyol  functionality
