How is Polyol Made?
How is Polyol Made?
The glycerol initiator is added to a reaction vessel along with PO and, in some cases, some EO. Under the influence of heat, pressure and catalyst the oxides are reacted with the initiator, producing the polyol
Glycerol +Propylene oxide + Ethylene oxide = Polyol
Small amounts of byproducts are removed from the polyol in subsequent treatment steps. Antioxidant stabilizer is added to the polyol to protect the polyol during the storage and transportation and also to reduce the risk of foam scorching.
