Polyester polyols are typically produced by the condensation reaction of a glycol with a dicarboxylic acid. There is a wide portfolio of Polyester Polyols with varied characteristics of Acidity, OH, functionality, molecular weights and chemical nature.

Aromatic polyester polyols are a critical component of polyurethane and polyisocyanurate foam systems. It can increase the product strength, heat resistance, flame retardant and other characteristics. 
With better performance than polyether polyol in flame retardant based foam plastics, high hydroxyl value polyester polyol is used to replace part of polyether polyol in polyurethane foam plastics industry.

Application

1.PUR fusion adhesive : PUR adhesive application improve adhesion strength, resistance to deformation, bonding profiles of substrates and modify the open time.
2.Flexible Packaging adhesive: polyester polyols deliver improved hydrolytic stability under acid and base conditions, flexibility, good pot life, and adhesion on substrate
3.Urethane Coating Resins: polyester polyols can be further compounded to radiation curable oligomers or polyurethane dispersions, offering hardness, flexibility, solvent resistance, and/or weatherability, depending on the grade.
4.Acrylate polymerization
5.Automotive – Noise, Vibration, Harshness (NVH)
6.Non-foaming emulsions
7.Fiberglass reinforced backing material
8.Manufactured housing adhesive
9.High quality polyurethane sealants – Sealer insulation (one-component foam)
10.Polyurethane Elastomers and Thermoplastic Polyurethanes (TPU): aliphatic polyesters contribute to excellent abrasion and tear resistance. They provide as well strong load bearing thus are commonly used in wheels, industrial and printing rolls as well as in mining equipment.
11.Rollers；Conveyor belts；Thermal break
12.Coating Adhesive Sealant Elastomer (CASE): High polyester polyols for CASE applications based on dimer fatty acids provide hydrophobicity, flexibility, elongation to the final polyurethane
13.Flexible PU Foam
