Vinyl fluorosilicone oil has recently made significant progress as a key cross-linking agent in the field of high-performance specialty elastomer materials. With its precisely controllable vinyl functional groups on the molecular chain, this material endows fluorosilicone rubber systems with finely tunable curing characteristics and outstanding comprehensive performance. It has become a core substance meeting the extremely stringent requirements for sealing materials in fields such as new energy vehicles and aerospace.

Research confirms that by finely adjusting the vinyl content (0.15%-0.8%), the crosslink density and final properties of the elastomer can be precisely controlled. Vulcanizates prepared using it achieve tensile strength of 12-16 MPa and tear strength of 45-55 kN/m, retaining over 90% of their performance after long-term aging at 250°C. Its extremely low swelling rate (<8%) in harsh media such as aviation fuel ensures long-term sealing effectiveness.

In the new energy vehicle sector, high-performance sealing materials based on vinyl fluorosilicone oil have become crucial for the safety of power battery packs. This material system provides battery modules with excellent resistance to electrolyte erosion, thermal shock, and flame retardancy. Real vehicle tests indicate that it can effectively delay the propagation of battery thermal runaway, buying valuable time for safety measures. In aircraft engine high-temperature sealing systems and rocket fuel lines, its derivative materials also demonstrate irreplaceable reliability.

As equipment advances toward higher power density and longer lifespan, the functional expansion of vinyl fluorosilicone oil continues to deepen. New-generation materials are endowed with additional functions such as high thermal conductivity, electrical conductivity, or electromagnetic shielding while maintaining excellent bulk properties, to meet the complex needs of integrated devices. Industry analysis indicates that as an upstream key material in the high-performance elastomer industry chain, its technological innovation will continuously radiate downstream, driving the upgrade of the entire high-end manufacturing ecosystem.
