Product Description

Ether polyol (referred to as polyether) is composed of initiator (compound containing active hydrogen group) and ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of a catalyst Prepared by polyaddition reaction. The one with the largest polyether yield is glycerol (glycerol) as the initiator and epoxy (generally PO and EO are used together), by changing the feeding method of PO and EO (mixed or separately added), the addition ratio, Various general polyether polyols can be produced under conditions such as the order of addition.

Polyether polyols are chemicals commonly used in the manufacture of general-purpose polyurethane foams, adhesives, and elastomers, among others. Special polyether polyols are also used as defoamers, surfactants, etc.
