Polyester polyols
What are polyester polyols?
Obtained via an ester condensation reaction, these are liquid ester oligomers for which polyvalent carboxylic acids (phthalic acid, succinic acid, etc.) and polyhydric alcohols (ethylene glycol, diethylene glycol, glycerin, etc.) are used as raw materials.
Characteristics of AWPC’s Polyester Polyol Business
- Many products have an aromatic ring as their main skeleton, and compared to aliphatic polyester polyols and polyether polyols exhibit the following properties:
- Excellent heat resistance
- Improved flame retardancy
- Increased resin strength
- All products are produced domestically.
- We can design products in accordance with customer requests. Please feel free to contact us.
Application
Raw material for polyurethane resin
- Spray-applied insulation for construction

- Sealants
- Synthetic leather
- Automobile seats
- Medical tubing
- Cushions, shock-absorbing materials
- Apparel textiles
- Sponges, cleaners, etc.
General properties
Its raw material being phthalic anhydride, a proprietary product, this series features a high concentration of aromatic rings.
