Definition of Polyether Defoamer

{
}

Polyether defoamer is a non-ionic surfactant with excellent defoaming, anti-foaming function, non-toxic, insoluble in water, soluble in organic solvents, can be used alone, can also be used as emulsion, which GPE type Particularly suitable for fermentation industry, PPE suitable for high temperature use.
The product has the advantages of polyether and silicone antifoaming agent, can defoaming and defoaming of different media, and its defoaming effect is 2 to 3 times stronger than that of conventional antifoaming agent, and has low toxicity, high surface activity, PH to adapt to a wide range of low surface tension, spreading speed and so on. The product can be dissolved in water at any ratio and can be subjected to high temperature sterilization treatment. It is widely used in the fields of antibiotic, vitamins and food processing, paper making, chemical industry, coating, building materials and detergents.
Polyether surfactants exist in the molecular state in water, high stability, non-toxicity, good compatibility with other types of surfactants, and have good anti-foaming effect, emulsifying ability and washing action, and have been widely used in many Industrial sectors and civilian washing, and other fields. With the development of the oil industry, polyether surfactant production and variety has been on the rise. The molecular weight of the polyether surfactants usually changes relatively large, its composition and structure are more complex, and these differences will significantly change the physical and chemical properties of the polymer.
