The general 201 silicone oil has good resistance to high and low temperatures, high flash point, low solidification point, low vapor pressure, good oxidation resistance and chemical stability. It can be used for a long time in the high temperature range of -50 ℃ to+200 ℃, isolated from air or in inert gas, and can be used for a long time at 200 ℃. It also has advantages such as low viscosity temperature coefficient, low surface tension, high compression rate, good shear resistance, and good transparency, It also has excellent electrical insulation performance, good arc resistance, corona resistance, moisture-proof performance, and good physiological inertness. Therefore, it has been widely used in various sectors of industry and agriculture, national defense industry, scientific research, and medical health. Our company particularly recommends using it as a defoamer, defoamer, lubricant (line oil), and dimethyl silicone oil for producing silicone rubber molds. In addition to possessing all the characteristics of 201 methyl silicone oil, due to its unique production process, 201 methyl silicone oil does not contain any residual catalysts or decomposition products, nor does it contain metal ions. Therefore, its non-toxic, odorless, and odorless characteristics are more prominent. It is non irritating to the human body, does not cause allergic reactions, and can be compatible with commonly used cosmetic components. These properties make silicone oil well used in cosmetic production, To improve the performance of cosmetics.
