The technology of modified fluorosilicone oil has achieved a breakthrough, leading the industry in high-temperature resistance and corrosion resistance

1. Technological Innovation: Inorganic-organic hybridization breaks through performance bottlenecks
Recently, a modification technology for fluorosilicone oil has passed the achievement evaluation, successfully breaking through the performance limitations of traditional materials in extreme environments. This technology uses methyl dichlorosilane containing hydrogen as the starting material. With the catalytic reaction of chloroplatinic acid, vinyl cack-type sesquiloxane is chemically bonded into the side chain of organic polysiloxane, and then fluoroalkylation treatment is carried out to produce a new type of modified fluorosilicone oil. Unlike the traditional physical blending method of adding nanoparticles, this chemical grafting process makes the product structure more stable and fundamentally solves the industry problem of the difficulty in balancing heat resistance and surface activity.


2. Performance leap: Both high-temperature resistance and low surface tension meet the standards
Experimental data show that the new modified fluorosilicone oil demonstrates outstanding comprehensive performance: the thermal decomposition temperature is significantly increased, and it can maintain chemical stability in high-temperature environments, solving the problem of easy decomposition of traditional silicone oil when heated. The surface tension is as low as 15-18 Mn /m. The synergistic effect of polyfluoroalkyl groups endows the material with excellent surface inertness, and its water and oil repellency performance is improved by more than 30% compared with ordinary fluorosilicone oil. Meanwhile, its tensile strength and chemical corrosion resistance both meet the standards of high-end industrial materials, and it can withstand the long-term erosion of strong corrosive media such as 98% sulfuric acid and 50% sodium hydroxide.


3. Scenario Implementation: Blossoming in multiple areas from electronic packaging to aviation sealing
With its outstanding performance, this modified fluorosilicone oil has initiated application verification in multiple high-end fields. In the electronics industry, its low surface tension property can be used as a hydrophobic and oleophobic coating for chip packaging, effectively enhancing the anti-fouling and insulation properties of microelectronic devices. In the aerospace field, it meets the requirements of seals and lubricants for high-temperature scenarios above 300℃, solving the lubrication and sealing problems of equipment in extreme environments. Preliminary tests in the medical field show that its biocompatibility indicators meet relevant standards, and it is expected to be used for surface modification of medical catheters in the future.


4. Industrial value: The easy availability of raw materials promotes the process of domestic production
Another major advantage of this technology lies in its feasibility for industrialization. All raw materials used in production are commercially available industrialized materials, which are widely available and have controllable costs, thus avoiding the predicament of relying on imported special raw materials. Industry experts point out that the mass production of this modified fluorosilicone oil will fill the gap in the domestic high-end fluorosilicone oil market, help achieve the domestic production rate target set in the "14th Five-Year Plan" for the development of new materials industry, and promote the independent control of the fluorosilicone material industry chain.
