Plastics and rubber are essential basic materials for the national economy, and polyether-modified silicone oils, as an excellent processing aid, play a significant role in the processing of plastics and rubber. This article will elaborate on their mechanisms, application advantages, and development trends.

I. Mechanisms

The molecular structure of polyether-modified silicone oils contains hydrophilic polyether segments and hydrophobic siloxane segments. This unique structure enables them to perform the following functions in the processing of plastics and rubber:

• Release: They can form a release film between the mold and the product, preventing sticking and improving release efficiency.

• Lubrication: They can reduce friction between plastic and rubber molecules, improving processing flow and production efficiency.

• Antistatic Properties: They can absorb moisture from the air, forming a conductive layer on the product surface to eliminate static electricity.

• Other Functions: They can also act as dispersants, anti-blocking agents, and plasticizers to improve the performance of plastics and rubber.

II. Application Advantages

Compared to traditional processing aids, polyether-modified silicone oils offer the following advantages:

• Significant Effects: They can significantly improve the processing efficiency and product quality of plastics and rubber.

• Excellent Stability: They maintain stable performance under high temperature and humidity conditions.

• Eco-friendly and Safe: They are safe for humans and the environment, meeting environmental requirements.

III. Development Trends

In the future, the application of polyether-modified silicone oils in plastics and rubber will exhibit the following trends:

• High Performance: Developing products with higher release, stronger lubrication, and better antistatic properties.

• Functionalization: Developing products with special functions such as flame retardancy, conductivity, and thermal conductivity.

• Green and Eco-friendly: Developing biodegradable, non-toxic, and environmentally friendly products.

Conclusion

As a high-performance, widely applicable processing aid, polyether-modified silicone oils play an increasingly important role in the plastics and rubber industry. With continuous technological advancements and increasing environmental requirements, they will undoubtedly make greater contributions to the development of the plastics and rubber industry.
