Sucrose-initiated Polyether Polyols For Rigid Foams
Sucrose-initiated Polyether Polyols For Rigid Foams
The product is a type of polymer synthesized by using sucrose (a natural carbohydrate) as the starter molecule, which undergoes polymerization with monomers such as propylene oxide (PO) and ethylene oxide (EO). Characterized by high functionality, high hydroxyl value, and a rigid structure, these polyols react with isocyanates to form rigid polyurethane foams with high crosslinking density and closed-cell structure. The resulting foam exhibits exceptional thermal insulation, dimensional stability, and mechanical strength, making it ideal for insulation applications.
