Polyether defoamer is mainly made of propylene glycol or glycerin, propylene oxide, ethylene oxide, etc. under the catalysis of potassium hydroxide to make a strong defoamer. it is characterized by environmental protection, high efficiency, no stains, and other advantages. lt is suitable for most of thesilicone-free defoaming agent industries as defoaming and anti-foaming needs.
Polyether defoamer is a non-ionic surfactant that has excellent defoaming and defoamer properties and is widely used in a variety of industrial and consumer products. Its main component is polyether, these polyethers have good surface activity, can reduce the surface tension of liquid, so as to effectively inhibit the formation of foam .
Application field
Coatings and inks : Adding polyether defoamer to coatings can improve the flatness and appearance .
Papermaking : The use of polyether defoamer in the pulp preparation process can reduce foam and ensure the quality of paper .
Food industry : polyether defoamer is used in some food processing to ensure product quality .
Agricultural chemicals : In the production of pesticides and fertilizers, polyether defoamer can reduce foam and improve product stability .
Fermentation and pharmaceutical : polyether defoamer is also widely used in fermentation and pharmaceutical industry because it is non-toxic, odorless and non-irritating .
Characteristics and advantages
efficient defoaming : can quickly destroy and eliminate the foam in the liquid, maintain good processing stability .
good compatibility : compatible with a variety of substrates and formulations, flexible use .
Environmental protection : generally does not contain silicon and organic solvents, in line with a variety of environmental standards .
non-toxic, odorless and non-irritating : in addition to industrial applications, it is also suitable for food, fermentation, cosmetics and pharmaceutical industries .
Preparation method and composition
Polyether defoamer can be divided into polyol type, fatty acid ester type and amine ether type according to the different initiator used for synthesis. Common products include GP type glycerol polyether, GPE type polyoxyethylene (polyoxyethylene) ether and PPG type polypropylene glycol .
