General Purpose Polyester Polyol (QCY-3152)

         From a chemical composition perspective, polyester polyols are polymer compounds formed by esterification, dehydration, and polymerization reactions of polyacids (such as adipic acid, isophthalic acid, etc.) and polyols (such as ethylene glycol, propylene glycol, etc.) under specific conditions. Its molecular structure contains both ester groups (- COO -) and multiple hydroxyl groups (-0H), which endows polyester polyols with unique chemical activity and physical properties. It is precisely because of the reactivity of hydroxyl groups that they can undergo chemical reactions with various compounds such as isocyanates and epoxy resins, forming cross-linked structures that bring excellent mechanical properties, chemical resistance, and weather resistance to the final product. For example, when preparing polyurethane materials. The hydroxyl group of polyester polyol reacts with the - NCO group of isocyanate to form the basic structure of polyurethane, which determines the performance of polyurethane products

foam plastic
One of the important raw materials of polyurethane foam. Rigid foamed plastic is commonly used in building insulation board. Its excellent thermal insulation performance can effectively prevent heat transfer, reduce building energy consumption, and improve energy utilization efficiency; Soft foam is widely used in cold storage, industrial plants and other places with high requirements for thermal insulation, while it is largely used in furniture, car seats and other fields to provide comfortable support and buffer for people. In the sofa cushion, the softness and elasticity of soft polyurethane foam can fit the body curve, reduce body pressure and improve comfort

elastomer
With high wear resistance, tear resistance, and good elasticity, it is used for manufacturing tires, seals, industrial accessories, and more. In tire manufacturing, polyester polyol based polyurethane elastomer can improve the wear resistance and anti-aging performance of the tire, and extend the service life of the tire. The seals use their good properties and chemical resistance to ensure the sealing effect under various working conditions and prevent the leakage of liquid or gas

Plays a role in plasticizing and increasing adhesion in adhesives, significantly improving the bonding strength and flexibility of the adhesive. Especially suitable for bonding wood, metal, and composite materials. In the wood processing industry, polyester polyol based adhesives can firmly bond wood together while maintaining a certain degree of flexibility to adapt to the thermal expansion and contraction of wood. In the bonding of metal and non-metal materials, their good bonding performance and chemical resistance ensure the reliability and durability of the bonding area
