Product Introduction
Polyester polyols are prepared by condensation polymerization of dicarboxylic acids with diols or polyols. During the preparation process, different combinations of raw materials and reaction conditions can be used to adjust the properties of polyester polyols, such as molecular weight, functionality, softness, and hardness.
