Silicone oil is widely used in many fields due to its excellent thermal stability, weather resistance, low surface tension and physiological inertness, especially in the plastics industry. Its unique physical and chemical properties make it an important additive for many plastic products.

1. Basic characteristics of silicone oil

Excellent lubricity: Silicone oil has excellent lubricity, which can reduce friction and improve the processing performance of plastics. This makes the plastic flow better and the molding effect better in processes such as extrusion and injection molding.

High temperature resistance: Silicone oil can remain stable at higher temperatures and is not easy to decompose. This feature can effectively prevent the degradation of materials in plastic products used at high temperatures.

Chemical stability: Silicone oil has good tolerance to many chemicals and is not easy to react with other chemicals. This allows it to maintain good performance in a variety of environments.

Low surface tension: The low surface tension characteristics of silicone oil enable it to penetrate into the microstructure of plastics, thereby enhancing the surface smoothness and appearance of plastics.

2. Specific application of silicone oil in plastics

Modified plastics: In the process of plastic modification, silicone oil is often used as a plasticizer, which can effectively improve the flexibility and ductility of plastics and improve their processing performance.

Surface treatment: Silicone oil can be used for plastic surface treatment to form a protective film, thereby improving the wear resistance and corrosion resistance of plastics.

Foam plastics: In the production of foam plastics, silicone oil, as a defoamer, can effectively control the generation of foam and improve the uniformity and stability of products.

Electrical insulation materials: Due to the excellent insulation properties of silicone oil, it is widely used in electrical insulation materials to ensure the safety and reliability of equipment.

3. Advantages of silicone oil

Environmental protection: Silicone oil is a non-toxic and harmless material that meets modern environmental protection requirements and is safe to use.

Economical: Although the cost of silicone oil is relatively high, the performance improvement and product quality improvement it brings can often reduce the overall cost in long-term use.

Versatility: Silicone oil can not only improve the physical properties of plastics, but also give them other properties, such as anti-static and anti-ultraviolet.

IV. Conclusion

The application characteristics of silicone oil in plastics make it an indispensable material in the modern plastics industry. By improving the processing performance, physical properties and durability of plastics, silicone oil provides strong support for the quality improvement of plastic products. With the advancement of science and technology, the application of silicone oil in plastics will become more extensive, bringing new opportunities for the development of the plastics industry.
