Low-viscosity Dimethyl Silicone Oil (5-50cst)

• In the Cosmetics Field: Low-viscosity dimethyl silicone oil has excellent fluidity and spreadability. It can quickly form a uniform protective film on the skin surface, making the skin feel smooth and delicate. It is often used in skin care products such as lotions, creams, and sunscreens. At the same time, it can also serve as a lubricant in hair care products, reducing the friction between hair strands, making the hair softer and easier to comb.
• In the Release Agent Field: During the production of plastic, rubber, and other products, low-viscosity dimethyl silicone oil can rapidly form a uniform isolation film on the surface of the mold, effectively preventing the products from sticking to the mold, facilitating the demoulding of the products, and improving production efficiency and product quality.

Medium-viscosity Dimethyl Silicone Oil (50-500cst)

• In the Electronic and Electrical Field: Medium-viscosity dimethyl silicone oil has good electrical insulation properties and heat dissipation performance. It is often used as an insulating, moisture-proof, and shock-proof material for electronic components. For example, in electronic devices such as transformers and capacitors, it can play the roles of insulation and heat dissipation, improving the stability and service life of the devices.
• In the Mechanical Lubrication Field: Medium-viscosity dimethyl silicone oil can be used as a mechanical lubricant for the lubrication and protection of various precision machinery, instruments, and meters. It can form a tough lubricating film on the metal surface, reducing the friction coefficient, minimizing wear, and improving the operation efficiency and precision of the machinery.
• In the Antifoaming Agent Field: In the production processes of the chemical, food, pharmaceutical, and other industries, a large amount of foam is often generated, which affects production operations and product quality. Medium-viscosity dimethyl silicone oil has good antifoaming performance. It can quickly break the foam and inhibit the generation of foam, ensuring the smooth progress of the production process.

High-viscosity Dimethyl Silicone Oil (above 500cst)

• In the Damping and Vibration Reduction Field: High-viscosity dimethyl silicone oil has high viscosity and elasticity, and can effectively absorb and dissipate vibration energy. It is often used in the manufacture of dampers, shock absorbers, and other products, and is widely applied in transportation vehicles such as automobiles, airplanes, and ships, as well as in engineering fields such as buildings and bridges, improving the stability and safety of equipment and structures.
• In the Sealing Material Field: High-viscosity dimethyl silicone oil can be used as a sealing material for the sealing of various machinery, pipelines, containers, etc. It can fill the sealing gaps, form a good sealing effect, and prevent the leakage of liquids and gases.
• In the Rubber and Plastic Modification Field: During the production of rubber and plastics, adding high-viscosity dimethyl silicone oil can improve the processing performance and physical properties of rubber and plastics, enhancing the flexibility, weather resistance, and wear resistance of products.

In conclusion, dimethyl silicone oil plays an important role in numerous fields due to its different viscosity characteristics. With the continuous development of science and technology, the research on the properties and applications of dimethyl silicone oil is also constantly deepening. In the future, it will show unique advantages in more fields and provide strong support for the development of various industries.
