Functional modification continues to break through, and ethyl silicone oil is deeply engaged in high-end scene applications

1.Multi-dimensional modification achieves performance upgrade
The ethyl silicone oil industry is achieving multi-dimensional functional breakthroughs through molecular structure design and formula optimization. In response to the heat conduction requirements, through the modification of nano-scale thermal conductive fillers, the thermal conductivity of the product has been increased to 400W/m · K, far exceeding the level of traditional products, while maintaining the low viscosity characteristic. In the field of electromagnetic compatibility, the developed integrated heat conduction and wave absorption product can simultaneously solve the heat dissipation and electromagnetic interference problems of electronic devices, and the silicone oil precipitation rate is controlled below 0.1%. Progress has been made in biocompatibility modification. Through the optimization of the purification process, the biological toxicity of the product has reached the ISO 10993 standard, meeting the strict requirements of the medical field.

2. Application in medical and aerospace scenarios
High-end modified products have achieved key applications in the medical and aerospace fields. Medical-grade ethyl silicone oil has passed the USP Class VI certification, with a purity of over 99.95%. It has been successfully applied in medical devices such as interventional catheters and implant coatings. The demand in this field is expected to increase by 18.7% year-on-year in 2024. In the aerospace field, extreme temperature-resistant modified products can operate stably for a long time in an environment ranging from -70 ℃ to 250℃, becoming core materials for spacecraft lubrication systems. Currently, they have entered the small-scale verification stage. These breakthroughs in high-end scenarios have driven the product's gross profit margin to over 45%.

3. Demand in the consumer electronics sector has exploded
With the development of consumer electronics towards high power consumption and miniaturization, the application demand for ethyl silicone oil continues to explode. In 5G base stations, optical modules and other equipment, low dielectric constant modified products effectively reduce signal loss and ensure the stability of equipment operation. In smart wearable devices, flexible modified products have become the core materials for waterproof sealing due to their excellent ductility and skin compatibility. In 2024, the demand for ethyl silicone oil in the consumer electronics sector will reach 220,000 tons, with a compound annual growth rate remaining above 12%. Among them, the proportion of functional modified products has exceeded 60%.

4. Focus on multi-functional integration in the future
In the future, the industry will focus on developing multi-functional integrated modification technologies to promote the development of products towards the direction of "one material with multiple functions". It is planned to develop integrated products with properties such as heat conduction, insulation and radiation resistance to meet the demands of emerging fields like new energy and quantum technology. Meanwhile, in the field of biomedicine, biocompatibility will be further optimized and applications in scenarios such as tissue engineering and drug carriers will be expanded. Functional modification will become the core of differentiated competition in the industry, driving ethyl silicone oil to move towards higher value-added fields.
