Polyester polyol


- Polyester polyol is one of the major raw materials of polyurethane system. Particularly, the aromatic polyester polyol has found wide-ranging applications in the rigid foam sector due to excellent flame retardancy and thermal insulation, and Woojo’s system has been well-recognized for its excellent performance.

● Features of Polyester Polyol
- Excellent Incombustible Property from the high Aromatic Content
- Highly mixable with foaming agent in a wide viscosity range
- Heat-resistant with low thermal transmission
- High Isocyanate Index in content
- High functional composite of Polyester Polyol

● Polyester Polyol


Application
- Raw materials for PIR system with high flame retardancy
- Raw materials for High functional system
- Raw materials for rigid polyurethane foam
- Raw materials for the system with low viscosity & excellent adhesion
