From Space to Kitchen: Fluorosilicone rubber usher in a new era of "all-round sealing", with application scenarios blooming in all directions

【 Aerospace "Black Technology "】 From" Tiangong "to" Yun-20 ", domestic fluorosilicone rubber has broken the foreign monopoly
At the beginning of 2025, with the delivery of another batch of domestically produced fluorosilicone rubber seals to the aerospace department, China has completely broken the long-term reliance on imports of high-end sealing materials. This material, hailed as "space-grade", has been successfully applied to the hatch of the Tiangong space station, the sealing system of the Shenzhou manned spacecraft, and the fuel lines of the Y-20 large transport aircraft, saving the country over 100 million yuan in import expenditures in total.

【 Five Major Characteristics 】 Why has fluorosilicone rubber become the "all-round Champion" of sealing materials?
1. Superhydrophobic "Lotus leaf effect
The contact Angle reaches 115-125° (while that of ordinary silicone rubber is only 105-110°), approaching the superhydrophobic property of lotus leaves
In high-humidity environments, it reduces water film adsorption and extends the service life of seals by 50%
An ideal choice for car wipers and sealing rings of deep-sea equipment
2. Ultra-low Friction "Lubricant"
The coefficient of friction has dropped from 0.4 of ordinary rubber to 0.25, reducing resistance by nearly half
The service life of dynamic seals is extended by 2 to 3 times, and the energy consumption of the transmission system is reduced by 5 to 8%
It is widely applied in fields such as robot joints and medical catheters
3. Anti-radiation "Protective shield
The new fluorosilicone rubber developed by Shandong University maintains stable performance under continuous irradiation with 300 KGy gamma rays
Nanomaterials efficiently eliminate free radicals generated by radiation, protecting the material structure from damage
Key protective materials for nuclear energy equipment and spacecraft
4. Self-lubricating "maintenance-free"
No lubricant is required within the range of -50℃ to 200℃, achieving "oil-free lubrication".
Aviation hydraulic systems and medical implant applications reduce the risk of contamination
The automotive braking system eliminates the grease process, reducing the unit cost by 0.5 to 1.2 yuan
5. Resistant to pollution and "easy to clean
The low surface energy characteristic reduces the pollutant adhesion rate by 70-90%
The cleaning frequency of food machinery molds has been reduced from twice per shift to once a day
The ion mobility of electronic device sealing rings in a sweat environment is reduced by 50%, enhancing reliability

【 Diverse Applications 】 From cutting-edge technology to daily life, fluorosilicone rubber is everywhere
1. New energy vehicles: The "Guardian" of the Three-Electric Systems
The sealed components of the battery, motor and electronic control system can withstand temperatures up to 180℃ and are resistant to electrolyte corrosion
In 2024, the demand will reach 3,200 tons, representing a year-on-year growth of 18.5%, accounting for 24% of the total consumption
Significantly enhance the waterproof performance of the battery pack and extend battery life by 20%
2. Ultra-high Voltage Power Grid: The "Safety Lock" for Power Transmission
State Grid plans to complete 40,000 kilometers of ultra-high voltage lines by 2025
Each kilometer of the line is equipped with approximately 3.2 tons of rubber products, generating a demand for 128,000 tons of fluorosilicone rubber
It is arc-resistant and anti-aging, ensuring the stable operation of the power grid and reducing maintenance costs
3. Medical Devices: "Invisible Guardians" in the Health Field
The coating of surgical instruments reduces tissue adhesion and lowers the risk of postoperative infection
The application of implants such as artificial joints and catheters reduces rejection reactions
Medical seals can withstand multiple disinfection methods, and their service life is increased by 50%
4. Smart Home: Guardian of a Comfortable Life
The service life of the refrigerator sealing strip has been extended from 2 years to 5 years, saving 15% of energy
The waterproof gaskets of smartwatches and mobile phones remain sealed after being soaked in water for 24 hours
The sealing rings of kitchen equipment are heat-resistant and oil-proof, reducing the cleaning frequency by 60%

【 Market Prospect 】 The "King of Sealing Materials" leads a new revolution in the industry
According to market research institutions' prediction, the global fluorosilicone rubber market size is expected to reach 170 million US dollars in 2025 and exceed 280 million US dollars by 2030, with a compound annual growth rate of approximately 8.5%. With the continuous breakthroughs in domestic technologies and the expansion of application fields, Chinese enterprises are transforming from "followers" to "leaders", seizing the initiative in the "detail battlefield" of high-end manufacturing.
Industry experts say that the wide application of fluorosilicone rubber not only enhances product performance and service life, but also significantly reduces the "full life cycle cost", injecting new impetus into the high-quality development of the manufacturing industry.
