Technological innovation leads to performance leaps, and fluorosilicone rubber has achieved multi-dimensional breakthroughs
Recently, the domestic scientific research field has made a series of progress in the development of fluorosilicone rubber materials. Through innovative means such as three-dimensional structure regulation and composite modification, the core performance of the materials has been significantly improved, providing key support for high-end equipment manufacturing and promoting the industry to accelerate its progress towards high performance.

1. The mechanical properties are doubled by regulating the three-dimensional structure
The research team, with the aid of highly sensitive characterization techniques, has for the first time achieved precise quantitative analysis of the stereochemical configuration of the quadruple of fluorosilicone rubber. Research has found that when the content of a specific monomer exceeds 58%, the material exhibits a high-order structure, the interplanar spacing decreases as the regularity increases, and the crystal growth mode changes from one-dimensional and two-dimensional structures to three-dimensional spherulite structures. After adding only a small amount of reinforcing fillers, the tensile strength of the high three-dimensional structured material increased by 197% compared with conventional products, with a significant self-reinforcing effect, providing the possibility for lightweight material design.

2. Upgraded ability to withstand extreme environments
In response to the shortcomings of traditional fluorosilicone rubber in terms of radiation resistance and high-temperature resistance, the R&D team adopted a mutual enhancement strategy. Through the synergistic effect of nanomaterials and polymer matrices, they efficiently eliminate the active free radicals generated by irradiation. The new composite material maintains stable mechanical properties under continuous irradiation with 300KGy γ -rays, and its temperature resistance range has been expanded to -50 ℃ to 230℃, making it the preferred sealing material in extreme environments. The application of this material in the field of X-ray detection imaging has achieved a spatial resolution of 19.0 lp mm−1, breaking through the application bottleneck in high-energy irradiation environments.

3. Expand application scenarios through functionalization
Through anionic ring-opening polymerization technology, researchers introduced highly polar fluorine-containing groups into the molecular chain and combined it with a green foaming process to prepare oil-resistant fluorosilicone rubber foam materials. This material features superhydrophobicity, high electrical conductivity and wide temperature range flexibility. It does not swell significantly in non-polar solvents such as diesel and can precisely respond to various deformation modes including compression and vibration. Its application in intelligent sensors and wearable devices has solved the detection problems in complex solvent environments.


4. The industrialization process is accelerating
With the gradual implementation of core technologies, fluorosilicone rubber products have formed a series layout, covering multiple categories such as high fluidity injection molding grade and high tear resistance extrusion grade. With policy support, the mechanism of industry-university-research collaboration has been continuously improved, and the penetration rate of materials in high-end fields such as aerospace seals and semiconductor packaging has been steadily increasing, providing technical support for domestic substitution.
