Silicone oil is a polyorganosiloxane with different polymer chains. It is made by hydrolysis of
dimethyldichlorosilane to obtain the initial polycondensation ring body, the ring by cracking,
distillation made of low ring body, and then the ring body, the head agent, the catalyst together
to get together to get the A mixture of different degrees of polymerization can be obtained by
removing the low boiling matter by distillation under reduced pressure.
The most commonly used silicone oil, organic groups are all methyl, said the base of silicone
oil. Organic groups can also use other organic groups instead of part of the methyl group to
improve the performance of silicone oil and apply a variety of different uses. Other common groups
are hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl and the like. In recent years, organic
modified silicone oil has been rapid development, there have been many special properties of
organic modified silicone oil.
Silicone oil is generally colorless (or light yellow), tasteless, non-toxic, less volatile
liquid. Silicone oil is insoluble in water, methanol, diol and -ethoxyethanol and can be miscible
with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene, slightly
soluble in acetone, dioxane, ethanol and alcohol The It has a small vapor pressure, a higher flash
point and a burning point, a lower freezing point. As the number of segments n varies, the
molecular weight increases and the viscosity increases, and the silicone oil can have a variety
of viscosities, from 0.65 centistokes to millions of centistokes. If a low viscosity silicone oil
is to be obtained, acid clay can be used as a catalyst and agglomerated at a temperature of
180 ° C or with sulfuric acid as a catalyst to produce a high viscosity silicone oil or viscous
material at a low temperature catalyst.
Silicone oil according to the chemical structure of methyl silicone oil, ethyl silicone oil,
phenyl silicone oil, methyl hydrogen silicone oil, methyl phenyl silicone oil, methyl
chlorophenyl silicone oil, methyl ethanol silicone oil, methyl trifluor Such as silicone oil,
methyl silicone silicone oil, methyl hydroxyl silicone oil, ethyl hydrogen silicone oil, hydroxyl
silicone oil, silicone oil, etc .; from the use of points, there are damping silicone oil,
diffusion pump silicone oil, hydraulic oil, Heat transfer oil, brake oil and so on.
Silicone oil has excellent heat resistance, electrical insulation, weather resistance,
hydrophobicity, physiological inertia and small surface tension, in addition to a low viscosity
coefficient, high resistance to compression) Some varieties also have radiation resistance
The performance. Silicone oil varieties and uses introduced silicone oil is a different degree
of polymerization chain structure of polyorganosiloxane. It is made by hydrolysis of
dimethyldichlorosilane to obtain the initial polycondensation ring body, the ring by cracking,
distillation made of low ring body, and then the ring body, the head agent, the catalyst together
to get together to get the A mixture of different degrees of polymerization can be obtained by
removing the low boiling matter by distillation under reduced pressure.
The most commonly used silicone oil, organic groups are all methyl, called methyl silicone oil.
Organic groups can also use other organic groups instead of part of the methyl group to improve
the performance of silicone oil and apply a variety of different uses. Other common groups are
hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl and the like. In recent years, organic
modified silicone oil has been rapid development, there have been many special properties of

Methyl silicone oil Product Description:
Methyl silicone oil is the most widely used in silicone oil, the most widely used varieties.
Colorless, tasteless, not volatile; insoluble in water, methanol, ethylene glycol, with benzene,
dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene miscible, with a small
vapor pressure, high flash point and Burning point. Methyl silicone oil has excellent heat
resistance, electrical insulation, weatherability, hydrophobicity, physiological inertia and small
surface tension, but also has a low viscosity coefficient, high compressibility. The main
purpose:
Used as insulation, lubrication, shock, dust, dielectric and heat carrier. It can also be used
as an additive for defoaming, stripping, painting and daily cosmetics. The excellent performance
of the products is widely used in the finishing of electronic appliances, building materials,
motor manufacturing, transportation, petrochemical, textile, printing and dyeing, lines, all kinds
of polyester and polyester cotton, polyester cotton Medical and health, aviation research and
military technology and other fields.
For the sewing thread processing, increase lubrication, can be in the high-speed sewing
machine on the line. For the soft finishing of the fabric, increase the lubricity of the fabric
, increase the smoothness of the fabric, fullness and flexibility.
Water-soluble silicone oil properties and uses:
The product is a silicone oil containing a variety of reactive genetically modified substances
that are completely soluble in water. For cotton, wool, silk, polyester and other fiber
finishing, so that it has a soft, breathable, smooth, anti-static and other effects. Used in
cosmetics to improve its smooth and smooth moisturizing effect. For the food industry to play
defoaming lubrication stripping and improve the gloss. In addition, it is also widely used in
plastics, rubber, petrochemical and many other industries. Main Specifications:
1. Appearance: slightly yellow to brown oily liquid
2.PH value: 6-8
