Silicone oil is a raw material with many special properties, such as low temperature viscosity coefficient, high and low temperature resistance, oxidation resistance, high flash point, low volatility, good insulation, low surface tension, no corrosion to metals, non-toxic, etc. Due to these characteristics, silicone oil has excellent effects in many applications. Among various silicone oils, methyl silicone oil is the most widely used and the most important type of silicone oil. Today, the editor will introduce the basic knowledge of silicone oil and take you to understand what silicone oil is and what it can be used for.

Silicone oil usually refers to linear polysiloxane products that remain in a liquid state at room temperature. It is generally divided into two categories: methyl silicone oil and modified silicone oil. The most commonly used silicone oil - methyl silicone oil, also known as ordinary silicone oil, has all organic groups of methyl. Methyl silicone oil has good chemical stability, insulation, and hydrophobic properties. It is obtained by hydrolysis of dimethyl dichlorosilane with water to form an initial condensed ring, which is then cracked and distilled to form a low ring. The ring, sealing agent, and catalyst are then mixed together to obtain a mixture of different degrees of polymerization. After vacuum distillation to remove the low boiling substance, silicone oil can be produced.

Usage: It has various viscosities. Has high heat resistance, water resistance, electrical insulation, and low surface tension. Commonly used as advanced lubricating oil, shock-absorbing oil, insulation oil, defoamer, release agent, polishing agent, isolation agent, and vacuum diffusion pump oil; Lotion can be used for car tire polishing, instrument panel polishing, etc. Methylsilicone oil is the most commonly used. Smooth and soft hand feel finishing applied to textile finishing after emulsification or modification. Emulsified silicone oil is also added to the shampoo of daily care products to improve the lubrication of hair. In addition, there are also ethyl silicone oil, methylphenyl silicone oil, nitrile containing silicone oil, polyether modified silicone oil (water-soluble silicone oil), etc.
