201 Methyl Silicone Oil or Polydimethylsiloxane
One, product introduction:
The 201 methyl silicone oil is a kind of novel silicone synthetic material.Appearance is colorless transparent oily liquid. It is the chemical composition of straight chain of poly (methyl siloxane, its formula is as follows:
Due to the stability of the silica keys and methyl hydrophobic, and the structure features of the methyl siloxane fit together to make silicone fluid has good heat resistance. High flash point, less volatile, small coefficient of viscosity, and compression strength, surface tension, chemical stability, good electrical insulation, and resistance to water moisture, of organisms (including humans) took place.In order to make the silicone fluid in other form a thin film surfaces or made into rubber solid matter, can use the high temperature (250-300 ℃) heat or add the appropriate catalyst (peroxide) is commonly used in curing processing. Methyl silicone oil used in the range of 50-180 ℃.
Different methyl silicone oil viscosity, their physical and chemical properties and parameters have some differences. The product with the size and viscosity of points, 201-10, 201-50, 201-100, 201-350, 201-500, 500-800, 201-1000.And other brands. Can also according to customer requirements, make other special viscosity specifications of the products.
Second, the purpose is introduced
1, in electrical and electronic industry, such as heat resistance, arc resistance, corrosion resistance, moisture-proof insulating medium.
2, in the chemical, pharmaceutical, food and other industrial departments as excellent heating medium.
3, in synthetic resin, oil processing, manufacturing, food and fermentation, papermaking process, such as high defoaming agent.
4, in precision machinery and instrument used to shock, damping, lubrication, force, etc.
5, in plastic and rubber molding processing, and food production for high temperature stripping agent.
6, in the glass, ceramic, metal, leather, fabrics, silk, and cement products material, such as surface treatment agent, has reached to enhance, drainage, corrosion resistance, mouldproof, smooth effect and so on.
7, in the paint, oil, cosmetics and other works as additive, in order to improve the flow flat, smooth performance, etc.
8, on health care, such as surgery, wound, injection processing, blood storage and oral medications, etc., has many USES.
Third, the technical indicators
Four, note
1.When heated, methyl silicone oil in contact with acid or alkali has certain damage, methyl silicone oil in higher than 200 ℃ is exposed to air, can happen oxidation precipitation corrosive such as formaldehyde low boiling, methyl silicone oil, although not spontaneous combustion under average temperature, but reach the ignition point (450 ℃ -- 450 ℃) or contact cause burning, make a lot of cotton in space shape quality of a material is silicon dioxide (a fire, you can use a wet sack on the sand or pressure out).
2.If methyl silicone oil packing storage is good, can never metamorphism (storage period is 5 years, exceed the time limi
