What is dimethyl silicone oil?

Silicone oil usually refers to linear polysiloxane products that remain liquid at room temperature. Generally divided into methyl silicone oil and modified silicone oil two categories. The most commonly used silicone oil - methyl silicone oil, also known as ordinary silicone oil, its organic groups are all methyl, methyl silicone oil has good chemical stability, insulation, good hydrophobic performance.
Dimethyl silicone oil is a colorless and transparent new synthetic polymer material with a variety of viscosities (5cps ~ 8 million cps) ranging from highly mobile liquid to thick semi-solid. This product has special smoothness, softness, hydrophobicity, good chemical stability, excellent electrical insulation and high and low temperature resistance. High flash point, low freezing point, and can be used for a long time at -50℃ ~ +200℃, small viscosity temperature coefficient, high compression rate, low surface tension, moisture resistance, moisture resistance, specific thermal conductivity is small.

Dimethyl silicone oil - Properties

Clear liquid to thick semi-solid. Colorless and odorless, molecular weight varies with the degree of polymerization. Insoluble in water, methanol, vegetable oil and paraffin hydrocarbon, slightly soluble in ethanol, butanol and glycerol, easily soluble in benzene, toluene, xylene, ether and chloroalkanes. The viscosity temperature coefficient is small, the compression rate is large, the surface tension is small, the moisture resistance is good, the specific heat capacity and the thermal conductivity is small. With excellent electrical insulation and heat resistance, high flash point, low freezing point, can be used in the temperature range of -50 ~ +200℃ for a long time.

Dimethyl silicone oil - Standard

Dimethyl silicone oil - Preparation method

This product is a linear polymer of dimethylsiloxane, containing polymerized dimethylsiloxane 97.0% ~ 103.0%. It has different viscosity due to different degree of polymerization. According to the different motion viscosity, this product is divided into 20, 50, 100, 200, 350, 500, 750, 1000, 12 500, 30 000 ten models.

Using dimethyldichlorosilane, water and solvent as raw materials, octamethylcyclotetrasiloxane was obtained by hydrolysis, neutralization and fractionation. Octamethylcyclotetrasiloxane was prepared by polymerization under the action of catalyst.

Dimethyl silicone oil - Uses

Used as defoamer in chemical, pharmaceutical and food industries;

Plastic and rubber molding processing used as efficient release agent; Used as polish for cars, furniture, floors and leather; Used as high temperature resistant dielectric liquid in electrical and electronic industry.

The glass, ceramic, metal, textile, cement products treated by this product, not only hate water, and anti-corrosion, anti-mildew, smooth surface, feel smooth.

Used in the cosmetics industry as head oil, hair cream, hairdressing agent, hair fixing agent and sunscreen;

It can also be used as a high and low temperature lubricant between various materials and a lubricant for plastic manufacturing and as a shockproof damping material for precision machinery and instruments
