The breakthrough in fluorosilicone oil technology leads the innovation of high-end materials

1.Key progress has been made in radiation-resistant fluorosilicone oil
The research team has developed a new type of fluorosilicone rubber through a mutual enhancement strategy, which still maintains stable performance under continuous irradiation with 300KGyγ -rays. This material effectively inhibits the damage of irradiation to molecular chains through a nanoscale free radical scavenging mechanism, providing a new solution for equipment sealing and protection in high-radiation environments such as the nuclear industry and aerospace. Its radiation resistance is more than three times that of traditional materials. It is expected to achieve mass production in 2026, filling the gap of high-end radiation-resistant materials in China.

2. Breakthrough in the preparation process of environmentally friendly modified fluorosilicone oil
A preparation method of modified fluorosilicone oil using methyl hydrogen-containing dichlorosilane as the raw material was recently disclosed. This process achieves the directional modification of fluorosilicone oil molecular chains by optimizing the polymerization reaction conditions in a mild environment. The surface tension of the product is as low as 20-25 Mn /m, which is 30% lower than that of traditional silicone oil. Its industrial production energy consumption has been reduced by 40%, and the recyclable rate of its products exceeds 90%, significantly enhancing the application competitiveness of fluorosilicone oil in fields such as environmentally friendly coatings and industrial lubrication.

3. Medical fluorosilicone oil breaks the import monopoly
Domestic enterprises have successfully developed medical-grade fluorosilicone oil, which has passed the ISO 10993 biocompatibility test and can replace imported products for lubricating surgical instruments. This material has a temperature resistance range of -50 ℃ to 260℃. Even after high-temperature sterilization, it can still maintain stable lubrication performance, reducing the return rate of instruments by 60%. Its non-toxic and non-allergenic properties meet the demands of highly sensitive equipment such as endoscopes and surgical robots. The cost is 30% lower than that of imported products, accelerating the localization process of medical equipment.

4. Application expansion in the aerospace field
Fluorosilicone oil demonstrates outstanding performance in the sealing parts of aviation fuel systems. Its resistance to alternating high and low temperatures (-60℃ to 200℃) and resistance to fuel erosion effectively solve the aging problem of traditional rubber materials. Through molecular-level design optimization, fluorosilicone oil-based seals have achieved a leakage rate of less than 0.01% after 30,000 cycles of testing. They have been applied to the fuel pipelines of new passenger aircraft and rocket propellant storage devices, contributing to the improvement of the reliability of China's aerospace equipment.
