Use of Polyether Polyol Use of Polyether Polyol

Polyether polyol is abbreviated as polyether. It is an oligomer whose main chain contains ether bond (—R—O—R—) and the terminal group or side group contains more than 2 hydroxyl groups (—OH). It is prepared by addition polymerization of an initiator (a compound containing an active hydrogen group) with ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of a catalyst. The largest polyether producers are all common polyether polyols. Polyether polyols are produced with glycerol (glycerol) as the initiator and epoxide, by changing the PO and EO addition methods (mixed addition or separate addition), addition ratio, addition order and other conditions.

The main purpose
1. Detergent or defoamer
L61, L64, F68 are used to prepare low-foam, high detergency synthetic detergent;
L61 and L81 are used as defoamers in the papermaking or fermentation industry;
F68 is used as an antifoaming agent in the blood circulation of artificial heart-lung machine to prevent air from entering.

2. Excipients and emulsifiers
Polyether has very low toxicity and is often used as a pharmaceutical excipient and emulsifier; it is often used in the oral cavity, nasal sprays, eyes, ear drops and shampoos.

3. Wetting agent
Polyether is an effective wetting agent and can be used in acid baths for fabric dyeing, photographic development and electroplating. F68 is used in sugar factories. Due to the increased water permeability, more sugar can be obtained.

4. Antistatic agent
Polyether is a useful antistatic agent, and L44 can provide long-lasting static protection for synthetic fibers.

5. Dispersant
Polyether is used as a dispersant in emulsion paints. F68 acts as an emulsifier during the emulsion polymerization of vinyl acetate. L62 and L64 can be used as pesticide emulsifier, as coolant and lubricant in metal cutting and grinding, and as lubricant during rubber vulcanization.
