What is polyether and what are the types of polyether? What does it do

Polyether is a linear polymer prepared by ring opening homopolymerization or copolymerization with ethylene oxide, propylene oxide and epoxy butane as raw materials under the action of catalyst. The outstanding characteristic of polyether is that its viscosity and viscosity index increase with the increase of polyether molecular weight. Moreover, polyether generally has low freezing point and good low-temperature fluidity.

Polyether is often used as drug excipient and emulsifier; It is often used in oral cavity, nasal spray, eye drops, ear drops and shampoo. Polyether is a wetting agent, which can be used in acid bath of fabric dyeing, photographic development and electroplating. When F68 is used in sugar factory, more sugar can be obtained due to the increase of water permeability. Polyether is a useful antistatic agent. L44 can provide lasting electrostatic protection for synthetic fibers. Polyether is used as dispersant in emulsion coatings. F68 is used as emulsifier in emulsion polymerization of vinyl acetate. L62 and L64 can be used as pesticide emulsifiers, coolants and lubricants in metal cutting and grinding. It is used as a lubricant when rubber is vulcanized. F38 can be used as emulsifier, wetting agent, defoamer, demulsifier, dispersant, antistatic agent, dust remover, viscosity regulator, foam control agent, leveling agent, gelling agent, etc. for the production of agricultural chemicals, cosmetics and drugs; It is also used in metal processing, cleaning, pulp and paper industry, textile processing (textile, finishing, dyeing, softening finishing) and water quality treatment; It is also used as a bleaching aid.
