Introduction of simethicone and instructions for use

1.What is simethicone

201 methyl silicone oil is a new silicone synthetic material. Appearance - colorless and transparent oily liquid. Its chemical composition is linear polymethylsiloxane and its structural formula is:

Due to stability of silicon-oxygen bond, hydrophobicity of methyl group, and structural characteristics of methylsiloxane complexes, methyl silicone oil has good thermal stability. Flash of light, non-volatile, low viscosity, high compressive strength, low surface tension, chemically stable, good electrical (insulation), water and moisture resistance, no harm to organisms (including humans) Toxic effect. In order for methyl silicone oil to form a thin film on surface of other objects or turn into a rubbery solid, it can be heated at high temperature (250-300°C) or added with an appropriate catalyst (usually peroxide) Curing. The temperature range for using methyl silicone oil is 50-180°C.

Methicone oils with different viscosities have certain differences in their physical and chemical properties and characteristic parameters. The product is classified by viscosity: 201-10, 201-50, 201-100, 201-350, 201-500, 201-800, 201-1000 and other grades. It can also be made into products with other special viscosity characteristics according to users' requirements.

2. Scope

1. It is used as an insulating medium to provide heat resistance, arc resistance, corrosion resistance and moisture resistance in electrical and electronic industries.

2. As an excellent heat transfer medium in chemical, pharmaceutical, food and other industries.

3. As an effective defoamer in synthetic resins, oil refining, food processing, fermentation, papermaking and other processes.

4. Used for shock protection, damping, lubrication, force transmission, etc. in precision machines and tools.

5. Used as a high temperature release agent in molding and processing of plastics and rubber, and in food industry.

6. As a surface treatment for glass, ceramics, metal, leather, fabric, silk and cement products, etc. to achieve effect of reinforcement, drainage, corrosion protection, mildew resistance and smoothness.

7. As an additive to coatings, oils, cosmetics and other products to improve leveling, smoothness and other properties.

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

3.Technical indicators

4.Attention needed

1. When methyl silicone oil is heated, it has a certain destructive effect when it comes into contact with acid or alkali. When methyl silicone oil is in contact with air at temperatures above 200 ° C, it may undergo oxidation and be precipitated by corrosive formaldehyde and other low-boiling substances. Although methyl silicone oil is not ignites spontaneously at normal temperatures, it will cause a fire when reaching combustion temperature (450°C-500°C) or on contact, and space will be filled with a large amount of cotton-like silica (in case of fire, sand or wet bags can be used to grind).

2. If packaging and storage of methyl silicone oil is good, then it can be stored for a long time without deterioration (the shelf life is approximately set at 5 years, after expiration date, it can be re-examined, and if no deterioration is found, it can continue to be called).
