Polyether Polyol
Polyether polyol (hereinafter referred to as polyether) is by the initial agent (groups of compounds containing active hydrogen) and ethylene oxide (EO) and propylene oxide (PO), epoxy butane (BO) in the presence of catalyst made by addition polymerization reaction. Polyether production so much for the glycerin (glycerin) as starting agent and epoxide (usually with EO and PO), by changing the PO and EO loading way (plus or separately and mixed), add more than, charging sequence and other conditions, produce all kinds of general polyether polyols.
