More about Polyol for PUF Panel
Polyols are used by Polyurethane industry to make polyurethane foam. Polyols are compounds with multiple hydroxyl functional groups available for organic reactions. Monomers such as glycerine, ethylene glycol, pentaerythriol and sucrose are reacted with ethylene oxide or propylene oxide to form polyether polyol & with dibasic acid these monomers are reacted to form polyester polyol.
Polyether Polyol is used in making rigid and semi-rigid PU foam. It is manufactured by ethoxylation/propoxylation of a polyhydric alcohol in the presence of a catalyst. Polyether Polyols are used for Pipe Insulation, Pipe Supports, Discontinuous Sandwich Panels & Blocks and Continuous Sandwich Panels
