Dimethicone is a transparent, colorless, tasteless, odorless and non-toxic oily liquid. According to the supply of dimethyl silicone oil, it has the characteristics of high flash point, low freezing point, good thermal stability, and high and low temperature resistance. It can be used for a long time at -50℃~+180℃. If it is isolated from air or in an inert gas, the temperature can reach 200℃. The surface silicon tension of the oil is very small, the compressibility is large, the shear resistance is good, the viscosity-temperature coefficient is small, and the dielectric loss is small; it is resistant to arcs, corona, and is not flammable; it is hydrophobic and moisture-proof, and it also has good physiological inertness. Dimethicone is non-toxic to the human body and is not decomposed by body fluids, so it is also widely used in medical and health care.
DimethiconeCan be used as defoaming agent and release agent:
Since dimethyl silicone oil has small surface tension and is insoluble in water, animal and vegetable oils and high boiling point mineral oils, it has good chemical stability and It is non-toxic and has been widely used as a defoaming agent in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, papermaking and other industries. As long as 10-100PPM silicone oil is added, it will have a good defoaming agent effect.
Because dimethyl silicone oil is non-sticky with rubber, plastics, metals, etc., it is also used as a release agent for the molding and processing of various rubber and plastic products. And used in precision casting. Using it as a release agent not only facilitates demoulding, but also makes the surface of the product clean, smooth and clear in texture.
