Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness, and small surface tension. Chemical structure of dimethyl silicone oil has a special structure, the main chain is an inorganic grade structure, is a non-polar molecule, so it is incompatible with water or substances containing polar atomic groups, so dimethyl silicone oil has low solubility in water and oil High activity can be obtained with a smaller amount of dimethyl silicone oil. Moreover, the surface tension is lower than that of water, surfactants, and general foaming liquids, and it is easy to spread on the surface of the foaming liquid, so the antifoaming ability is relatively strong.
