Product Description
Polyether polyols, referred to as polyethers, are oligomers containing ether bonds (-R-O-R -) in the main chain and containing more than 2 hydroxyl groups (-OH) in the end group or side group, which are prepared by the addition polymerization reaction of the initiator (a compound containing active hydrogen groups) with ethylene oxide (EO), propylen e oxide (PO), and ethylene oxide butan e (BO) in the presence of a catalyst. Polyether polyols with glycerol (glycerol) as starting agent and epoxide are the largest in production. By changing the feeding method of PO and EO (mixed or separately added), adding ratio, adding order and other conditions, a variety of general polyether polyols are produced.
