This polymer is an aliphatic-aromatic polyester resin produced from terephthalic acid, sebacic acid, neopentyl glycol, and ethylene glycol. It is mainly used as a polyester resin intermediate for coatings, powder coatings, adhesives, inks, and industrial polymer formulations. It provides good flexibility, weather resistance, chemical resistance, and thermal stability.
