polyether polyol (polyether for short) is an organic polymer, which is prepared by addition polymerization reaction of starting agent (compound containing active hydrogen group) with ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of catalyst. The largest yield of polyether is to use glycerol (glycerol) as the starter and epoxide (usually PO and EO are used together), by changing the feeding method of PO and EO (mixed addition or separate addition), addition ratio, The feeding sequence and other conditions produce various general polyether polyols.

Three Functions and Uses

of Polyether Polyols 1. Can be used to produce rigid foams, they are available in aromatic and aliphatic versions. In addition, they also have mixed aliphatic aromatic versions, usually made of recycled raw materials, usually polyethylene terephthalate (PET), which are widely used in refrigerators, refrigerators, refrigerated trucks, heat insulation panels, pipe insulation and other fields

2. Mainly used in the production of polyurethane soft foam, polyurethane rigid foam and coatings, adhesives, sealants, elastomer (CASE) products

3. Production of foam stabilizers, paper industry defoamers, crude oil demulsifiers, high-efficiency low-foam detergents, lubricants, quenching agents, latex foaming agents, rubber lubricants and surfactants.
