Hot melt adhesives can be produced from various materials, one of which is polyester resin. Polyester hot melt adhesives have similarity with polyamide hot melt adhesives, and both are widely utilized in high-performance applications. Compared with polyamide hot melt adhesives, polyester hot melt adhesives take advantage in higher moisture resistance, though they have lower strength and melting point. Polyester hot melt adhesives are widely applied in many fields, and can be utilized individually or with other additives in the formulation according to different product requirements. Due to their high tensile strength and good performance at high temperatures, their most common use is for adhesion of fabrics. Besides, the high demand from protective clothing applications such as protective jackets, hazmat suits, and fabric applications with high temperature tolerance also spawns niche application market because of their advantages in quick curing time, low VOC emissions, and easy application through glue guns. However, it is a little difficult to produce polyester hot melt adhesives, and thus the replacement with cheaper hot melt adhesives is necessary. The increasing demand from textiles, book-binding, auto vehicle, transportation, shoes, and packaging industries continues promoting polyester hot melt adhesive market in Asia Pacific. In addition, formation development for new applications in packaging and the reduction of using harmful adhesives based on solvent will expand the polyester hot melt adhesive market around the globe in the long run.
