Polyether defoamer is a kind of non-ionic surfactant, which has excellent defoaming and foam inhibition function, non-toxic, insoluble in water, soluble in organic solvents, can be used alone, can also be used as emulsion.
Polyether defoamer is one of the most important varieties of defoamer products, with non-toxic, odorless, non-irritating and easy to disperse in water and other characteristics, in addition to general industrial applications, but also can be used in food, fermentation, cosmetics and medicine and other industries, is silicon defoamer can not be replaced.
Polyether defoamer can be divided into polyol type, fatty acid ester type and amine ether type according to the different initiators used in synthesis, among which polyol type and fatty acid ester type are widely used. The production of polyether defoamer in China began in 1969 and was first applied to antibiotic fermentation. These products mainly include GP type glycerol polyether, GPE type polyoxyethylene (polyoxypropylene) ether and PPG type polypropylene glycol.
Performance
