In the high-altitude, low-temperature environments of aerospace applications, in the high-temperature, oil-contaminated conditions of automotive engines, and in the highly corrosive media of petrochemical industries, a seemingly small sealing component directly determines the safe operation and service life of equipment.  When ordinary sealing materials frequently fail, a special material possessing multiple superior properties—low-pressure deformable fluorosilicone rubber—is becoming a crucial choice for several high-end industries. What "cutting-edge technologies" does it possess, and what industry pain points can it solve? Today, let's explore this in detail.



As a type of specialized synthetic rubber material, the core advantage of low-pressure modified fluorosilicone rubber compound lies in its "all-around adaptability," breaking through the limitations of traditional materials in terms of performance, and demonstrating exceptional capabilities, especially in extreme environments.  First and foremost, its most remarkable feature is its ultra-wide operating temperature range, easily withstanding drastic temperature fluctuations from -60℃ to 200℃. In extremely cold high-altitude environments, it will not become brittle or crack due to low temperatures, maintaining excellent flexibility throughout.Even in the high-temperature engine compartment, it will not soften or deform due to the heat, and its sealing performance remains rock-solid. This characteristic of being "resistant to extreme cold and able to withstand high temperatures" makes it stand out in environments with large temperature fluctuations.

In addition to excellent temperature resistance, low-pressure modified fluorosilicone rubber also possesses outstanding resistance to oil, solvents, and chemical media. In industrial production, sealing components often need to be in prolonged contact with corrosive media such as fuels, lubricants, and various chemical reagents. Ordinary materials are easily corroded, leading to seal failure and equipment leakage, which not only affects production efficiency but may also pose safety hazards.  However, thanks to its special molecular structure, low-pressure modified fluorosilicone rubber can effectively resist the erosion of these media. Even with prolonged contact, it will not experience swelling, aging, or cracking, greatly improving the reliability and durability of the sealing system.

The balance between strength and resilience is another key indicator of sealing material performance. Low-pressure modified fluorosilicone rubber compounds possess both good mechanical strength and excellent resilience. This means that after being compressed and deformed, it can quickly return to its original shape, maintaining a tight seal against the sealing surface and effectively preventing media leakage. Whether in high-frequency vibrating automotive components or in valve seals requiring repeated opening and closing, its excellent resilience ensures a stable sealing effect over the long term, preventing sealing failure due to material fatigue.

Excellent insulation is another important advantage of low-voltage modified fluorosilicone rubber. In applications requiring extremely high insulation performance, such as electronic and electrical equipment and aerospace instruments, it not only provides sealing but also offers excellent insulation protection, preventing equipment malfunctions caused by leakage or short circuits.  At the same time, it also possesses excellent selective permeability, allowing specific gases to pass through while blocking liquids and other impurities. This characteristic gives it unique application value in certain special gas separation and breathable sealing scenarios.

Thanks to its comprehensive and superior performance, low-pressure modified fluorosilicone rubber has deeply penetrated into various high-end fields such as the aerospace industry, automotive industry, and petrochemical industry, becoming a crucial material support for promoting high-quality industrial development. In the aerospace industry, it is a core material for aircraft components and seals that come into contact with fuel and lubricants, and is also used for overall fuel tank sealing. Aerospace equipment demands extremely high levels of safety and reliability from materials. The excellent performance of low-pressure modified fluorosilicone rubber effectively ensures the sealing safety of aircraft fuel systems in extreme high-altitude environments, safeguarding flight safety.

In the automotive industry, low-pressure modified fluorosilicone rubber compounds are also widely used, appearing in critical components such as vehicle sealing rings, oil seals, diaphragms, and valve linings.  As the automotive industry moves towards higher-end and more intelligent vehicles, the demands for high temperature resistance, oil resistance, and long service life of components are increasing. This material perfectly adapts to the high-temperature and oily environment of the automotive engine compartment, effectively extending the service life of sealing components, reducing vehicle maintenance frequency, and minimizing problems such as fuel leakage and excessive exhaust emissions caused by seal failure. This contributes to achieving the dual goals of energy conservation, environmental protection, and safety and reliability in the automotive industry.

In the petrochemical industry, various equipment such as pumps, valves, and storage tanks need to operate under conditions of high temperature, low temperature, and highly corrosive media for extended periods. Sealing problems have always been a challenge in this industry. Low-pressure modified fluorosilicone rubber compounds, with their excellent high-temperature resistance, low-temperature resistance, and chemical resistance, can precisely match the sealing requirements of this equipment, effectively addressing the shortcomings of traditional sealing materials such as susceptibility to corrosion and short lifespan. This ensures the stable operation of petrochemical equipment, reduces production safety risks, and provides strong support for efficient production in the petrochemical industry.
