Vinyl fluorosilicone oil has recently made significant technological progress in the field of high-performance elastomer materials. With its precisely controllable vinyl functional groups and unique molecular structure design, this material has become a core cross-linking agent for preparing specialty fluorosilicone rubbers used in extreme environments. It provides innovative solutions for aerospace engine sealing, new energy power battery encapsulation, and high-end electronic protection, significantly enhancing the reliability and safety of related equipment under harsh operating conditions.

Research data shows that through fine-tuning of vinyl content (0.15%-0.8%) and molecular weight distribution, vinyl fluorosilicone oil enables highly controllable curing process kinetics. Vulcanized rubber prepared using it exhibits exceptional comprehensive performance: tensile strength reaches 12-16 MPa, tear strength is 45-55 kN/m, and performance retention exceeds 90% after 500 hours of aging at 250°C. In harsh media such as aviation fuel, its volume expansion rate remains stably controlled within 8%, demonstrating extraordinary resistance to chemical corrosion.

In the aerospace sector, the material has become a key foundational material for next-generation aircraft engine high-temperature sealing systems and rocket fuel line connectors. Actual flight data indicates that sealing components manufactured with this material show no signs of performance degradation after over 3,000 flight cycles under severe conditions including drastic temperature fluctuations from -60°C to 280°C and high vibrational loads. In the new energy vehicle power battery field, high-performance sealants based on vinyl fluorosilicone oil have been applied on a large scale for encapsulating high-energy-density battery modules. Their excellent resistance to electrolyte erosion and thermal shock extends the thermal runaway propagation time in extreme safety tests such as nail penetration and crush tests to 3.5 times that of traditional solutions, providing a critical time window for occupant evacuation.

As equipment evolves toward higher power density and greater adaptability to extreme environments, a series of achievements have been made in the functional expansion of vinyl fluorosilicone oil. Through modification of the molecular backbone, new-generation materials achieve thermal conductivity up to 0.7 W/(m·K) while maintaining excellent mechanical and media resistance properties, providing material-level solutions for high-power motor insulation and battery thermal management. Industry experts point out that the continuous innovation of this core material not only represents the highest level of specialty elastomer cross-linking technology but will also serve as a critical cornerstone propelling strategic industries such as space exploration, clean energy, and high-end electronics toward higher performance and reliability, with broad market prospects.
