Which one has better defoaming effect, polyether defoamer and silicone defoamer?
Today, let's discuss which one of polyether defoamer and silicone defoamer has better defoaming effect?
Polyether Antifoam:
Polyether antifoam mainly includes three kinds of linear polyethers, polyethers with alcohol or ammonia as initiators and polyether derivatives with end-group esterification. The biggest advantage of polyether defoamer is its strong anti-foaming ability. In addition, some polyether defoamer have excellent properties such as high temperature resistance, strong acid and alkali resistance. The disadvantages of polyether defoamer are that the use conditions are limited by temperature, the use field is narrow, the defoaming ability is poor, and the foam breaking rate is low.
Polyether antifoam is often used in fermentation, biological water treatment, aeration tanks, cleaning agents, lye, makeup, reverse osmosis water treatment, extraction, chemical and other industries. Common types of polyether antifoam are GP type glycerol polyether, GPE type polyoxyethylene (polyoxypropylene) ether and PPG type polypropylene glycol.
Silicone Defoamer:
Silicone defoamers have the advantages of strong defoaming performance, rapid foam breaking ability, low volatility, non-toxic to the environment, and wide application range. Therefore, silicone defoamers have broad application prospects and huge market potential. . The disadvantage of silicone defoamers is their relatively poor anti-foaming properties. In addition, silicone defoamer is relatively advantageous in price.
Silicone antifoam is widely used in adhesives, daily chemical cleaning, washing, water treatment, agriculture, food, desulfurization, oil field drilling, mining and other industries to defoaming and defoaming because of its good defoaming.
Different defoamers need to be selected for different industries. If it is quick to break and defoamer, you can choose a silicone defoamer. If it is good for foam suppression and good transparency, it is recommended to choose a polyether defoamer.
