Fluorosilicone rubber breaks through performance bottlenecks, and new materials unlock new application scenarios in extreme environments

1.Breakthroughs in radiation-resistant technology have empowered the field of high-energy ray detection
The performance shortcomings of fluorosilicone rubber in high-energy irradiation environments have been successfully overcome. The latest research, through a mutual enhancement strategy, utilizes nanomaterials to efficiently eliminate active free radicals generated by irradiation. At the same time, it enhances stability by means of the ion-dipole interaction between trifluoromethyl dipoles and nanomaterials, enabling the new fluorosilicone rubber to maintain excellent performance under continuous 300 KGy γ -ray irradiation. This breakthrough not only enhances the mechanical stability of the material in extreme environments, but also expands its applications in fields such as the nuclear industry and radiological medicine. For example, when it is used as an X-ray detection imaging material, a spatial resolution of 19.0 lp mm⁻¹ and a detection limit of 3.78 µGy s⁻¹ can be achieved. It provides a new material solution for the upgrade of high-energy ray detection technology.

2. The three-dimensional structure regulation achieves a significant improvement in self-reinforcing mechanical properties
By optimizing the proportion of monomers to regulate the stereochemical structure, the mechanical properties of fluorosilicone rubber have achieved a leapfrog improvement. The research found that the stereoregularity of polymethyltrifluoropropyl siloxane (PMTFPS) has a significant impact on its crystallization behavior and mechanical properties. When the content of cis-D3F exceeds 58%, the material presents a high order structure, and the crystal growth mode changes from one-dimensional and two-dimensional to three-dimensional spherulites. The highly regular elastomer developed based on this mechanism exhibits a significant self-reinforcing effect. With only 5 parts of silica added for reinforcement, its tensile strength is 197% higher than that of ordinary products, providing a better choice for high-strength demand scenarios such as aerospace seals and high-pressure equipment gaskets.

3. The popularization of continuous production processes reduces costs and increases efficiency, promoting industrial upgrading
Technological innovation in production is reshaping the industrial landscape of fluorosilicone rubber. The penetration rate of continuous bulk polymerization technology is rapidly increasing, expected to rise from 18% in 2022 to 45% in 2030. This technology can reduce production energy consumption by 22% and cut production costs by 15%. Meanwhile, the construction of digital factories is accelerating. The application of industrial Internet platforms has increased production efficiency by 25%. Leading enterprises have raised the product qualification rate from 92% to over 98% through full-chain digital control. The iteration of production processes not only alleviates the cost pressure brought about by fluctuations in raw material prices, but also lays a foundation for the large-scale supply of high-end products.

4. Accelerate the certification of biocompatibility for medical-grade materials to break through application limitations
The localization process of medical-grade fluorosilicone rubber has been expanding simultaneously with its application scenarios. With domestic materials successively obtaining FDA certification, their application proportion in high-end medical devices such as artificial organs and pharmaceutical catheters has been continuously increasing. The medical-grade market size is expected to exceed 1.2 billion yuan by 2025. This type of material, with its excellent biocompatibility and resistance to damp heat sterilization, has solved the problem of easy rejection reactions caused by traditional rubber in human implantation scenarios. Currently, it has been stably applied in niche fields such as artificial valves and drainage tubes, and the import substitution rate has increased by 30 percentage points compared with 2020.
