From small automobile oil seals to large aircraft fuel tank seals, an invisible "sealing code" is guarding the core equipment of various industries - this is low-pressure modified fluorosilicone rubber. With its comprehensive properties of high and low temperature resistance, oil resistance and strong elasticity, it has written a legend of "reliable protection" in aviation, automobile, petrochemical and other fields.

In the aviation industry, it is the "patron saint of fuel systems". Aircraft fuel pipelines and seals face temperature differences from -50°C to 150°C every day and come into contact with special oils such as aviation kerosene. Components made of fluorosilicone rubber can maintain a sealed shape at extreme temperatures and resist fuel erosion, ensuring no oil leakage during flight. The use of it in key parts such as the overall sealing of the fuel tank has raised the safety factor to a new level.

The automotive industry is its "main battlefield". As automobiles have higher requirements for reliability, oil seals and sealing rings in the engine compartment need to cope with high temperatures (the temperature near the engine often exceeds 150°C) and immersion in engine oil and gearbox oil at the same time. Components made of this material will not harden and crack during long-term use, nor lose elasticity due to swelling, which greatly prolongs the replacement cycle of core components of automobiles and reduces maintenance troubles.

In the petrochemical field, it is an "anti-corrosion pioneer". In oilfield exploitation and chemical production, equipment such as pumps, valves, and oil tanks often come into contact with highly corrosive media such as crude oil and acid-base solutions. Ordinary rubber will age and fail in a few days. However, fluorosilicone rubber seals can "stick to their posts" in high-temperature and high-corrosion environments, with compression set ≤10% (after being pressed at 177°C for 22 hours), which means that they can still return to their original shape after long-term compression, and the seal will not fail.

Medical and health care and military industries are also inseparable from its help. Seals in medical equipment need to be resistant to disinfection solvents (such as alcohol, high-temperature steam) and not release harmful substances; sealing strips for special parts of military equipment need to remain stable in low-temperature, oil-stained, acid-base environments, and it can easily meet these needs.

Usage tips: For fuel contact scenarios, it is recommended to choose 50A or 60A hardness models to balance sealing performance and durability; confirm the vulcanization process before processing (first stage 170°C × 15min, second stage 200°C × 4h) to avoid parameter errors affecting performance; it is recommended to do compatibility test before contacting chemicals to ensure erosion resistance effect.
