A large class of alcohols containing two or more hydroxyl groups in their molecules are called polyols. Based on the source of their raw materials, they can be divided into plant-based polyols and petrochemical-based polyols. As an emerging green material, plant-based polyols have seen their application fields expand to most polyurethane products as application technologies mature.

 

I. Product Functional Category and Applications

Polyols are the main raw materials for preparing polyurethane adhesives. Due to their different molecular structures, their properties vary. Their specific application characteristics are as follows:

1. Polyurethane adhesives synthesized from polyols with regular structures have strong crystallinity and high bonding strength.

2. Polyurethane adhesives prepared from polyols with side-chain methyl groups have good gloss and brightness;

3. Polyurethane adhesives prepared using polyether-type polyols have lower glass transition temperatures, better flexibility, and better water resistance.
