Chemical Composition
Polyester polyol
Advantages
- medium molecular weight
- high degree of flexibility
- inherent flame retardancy, which ensures that additional flame retardants are not required to be added to the formulation
- a green alternative to the petrochemical polyols
- formulations prepared using this bio-based polyol exhibit properties comparable to those of petrochemically based polyesters
- fast setting behaviour
Other Applications
reactive hot-melt adhesives
Handling
It has 100% renewable content.
