Methyl silicone oil is a novel organosilicon synthetic material. Appearance is colorless and transparent oily liquid. Its chemical composition is linear polymethylsiloxane. Due to the stability of the silicon-oxygen bond, the hydrophobicity of the methyl group, and the structural characteristics of the methylsiloxane complex, the methylsiloxane oil has good heat resistance. Flashing light, non-volatile, small viscosity coefficient, large compressive force, small surface tension, chemical stability, good electrical (insulation) properties, and water and moisture resistance, non-toxic to living organisms (including humans). In order to make methyl silicone oil form a film on the surface of other objects or make a rubber-like solid substance, it can be cured by heating at high temperature (250-300 ° C) or adding an appropriate catalyst (usually peroxide). The temperature range of methyl silicone oil is 50-180℃. Methyl silicone oils with different viscosities also have certain differences in their physical and chemical properties and characteristic parameters.

Application range:

1. It is used as an insulating medium for temperature resistance, arc resistance, corrosion resistance and moisture resistance in electrical and electronic industries.

2. It is an excellent heat carrier in chemical, pharmaceutical, food and other industrial sectors.

3. It can be used as a high-efficiency defoamer in synthetic resin, oil processing, food manufacturing, fermentation, papermaking and other processes.

4. It is used for shock resistance, damping, lubrication and force transmission in precision machinery and instruments.

5. It is used as a high-temperature mold release agent in the molding of plastics and rubber, as well as in food production.

6. As a surface treatment agent on glass, ceramics, metal, leather, fabric, silk and cement products, etc., to achieve the effects of enhancement, drainage and corrosion resistance, mildew resistance, and smoothness.

7. It is used as an additive in paints, oils, cosmetics and other products to improve the properties of leveling and smoothness.

8. It has many uses in medical treatment, such as surgery, wound dressing, injection treatment, blood storage and oral medicine.

requires attention:

1. When methyl silicone oil is heated, it will have a certain destructive effect in contact with acid or alkali. When methyl silicone oil is in contact with air above 200 °C, it can oxidize and precipitate corrosive low-boiling substances such as formaldehyde. Methyl silicone oil Although it will not spontaneously ignite under normal temperature, it will burn when it reaches the burning point (450℃-500℃) or contact, so that the space is filled with a large amount of cotton wool-like texture silica (when a fire occurs, it can be crushed with sand or wet sacks) .

2. If the methyl silicone oil is well packaged and stored, it will not deteriorate for a long time (the storage period is tentatively set for 5 years, and it can be re-inspected if it is overdue. If no deterioration is found, it can continue to be named).
