De-foaming Agent

Silicone oil defoamer has strong chemical stability, no physiological toxicity, is difficult to react with other substances, has a certain affinity for foaming substances containing alkyl groups, and has significant defoaming effects in a variety of foaming liquids. Its surface tension is lower than foaming liquids such as water (73mN/m) and vegetable oil (35-40mN/m). The general surface tension is 16-21mN/m. This makes the force between defoaming molecules small, which is conducive to adsorbing or displacing foam, and quickly diffusing in the foaming liquid to achieve the purpose of rapid defoaming. It also has the advantages of chemical and physiological inertness.
