What are the functions of polyether polyols

Polyether polyols (abbreviated as polyethers) are organic polymers composed of active hydrogen groups and ethylene oxide (EO), propylene oxide (PO), and butane oxide (BO). When a catalyst is present, they are prepared through an addition reaction. The largest production of polyether is glycerol (glycerol) and epoxides (usually used in combination with PO and EO). By changing the feeding method (mixed or separate), dosage ratio, and feeding sequence of PO and EO to produce various general polyether polyols.
Three functions and uses of polyether polyols
1. It can be used to produce aromatic and aliphatic versions of hard foam. In addition, they also have mixed fatty aromatic versions, usually made from recycled raw materials, usually polyethylene terephthalate (PET), widely used in fields such as refrigerators, refrigerators, refrigerated trucks, insulation boards, pipeline insulation, etc
2. Mainly used for the production of polyurethane soft foam, polyurethane hard foam, coatings, adhesives, sealants, and elastomer (CASE) products
3. Produce foam stabilizer, paper industry defoamer, crude oil demulsifier, high-efficiency low foam detergent, lubricant, quenchant, latex foaming agent, rubber lubricant and surfactant.
