Simple summary: It is the basic raw material for manufacturing polyurethane elastomers (PU rubber), which reacts and solidifies with chain extenders to produce a high elasticity and wear-resistant polymer material with properties between ordinary rubber and engineering plastics.
1、 Conventional melt condensation method Feeding: Dicarboxylic acid and polyol are fed into the reaction vessel at once, with an appropriate excess of alcohol; Heating esterification: esterification reaction occurs at 140-200 ℃, generating water and continuously evaporating it;
Polyester polyol is one of the core raw materials for preparing polyurethane (PU). It is obtained by dehydration condensation of dicarboxylic acids (adipic acid, phthalic anhydride, etc.) and diols (ethylene glycol, 1,4-butanediol, etc.). The main chain of the molecule contains ester bonds (- COO -), and the end of the molecule has active hydroxyl groups (- OH). The hydroxyl groups can react with
1、 Film forming function (the most basic function) After drying and curing, polyurethane dispersion or solvent based PU resin will form a continuous and flexible polymer film, which forms a protective film on the surface of leather or artificial leather substrate, firmly fixing fillers, colorants, and additives to prevent pigment and powder from falling off.
