Sorbitol-initiated Polyether Polyols For Rigid Foams
Sorbitol-initiated Polyether Polyols For Rigid Foams
The product is a high-functionality polyol synthesized using sorbitol (a six-hydroxyl sugar alcohol derived from glucose hydrogenation) as the starter, and through ring-opening polymerization with monomers like propylene oxide (PO) and ethylene oxide (EO). When reacted with isocyanates, they form rigid polyurethane foams with superior mechanical strength, thermal resistance, dimensional stability, and closed-cell content.
