Aromatic Specialty Polyester Polyol is a high‑performance branched or linear polyester polyol synthesized from aromatic dicarboxylic acids (phthalic anhydride, isophthalic acid) and polyhydric alcohols. It contains aromatic structures in the molecular chain, providing high hardness, good heat resistance, excellent chemical resistance, strong adhesion and low cost. It is mainly used to make rigid polyurethane foam, insulation materials, PU coatings and composite adhesives.
