As a high-end silicone material, vinyl fluorosilicone fluid exhibits exceptional performance thanks to its unique molecular structure. Its molecular chain contains both fluorine atoms and vinyl groups, inheriting the chemical resistance and high- and low-temperature durability of fluorosilicone while also endowing it with excellent cross-linking reactivity through the vinyl group. This makes it a key material in high-end fields such as aerospace, electronics, and electrical engineering.
In terms of temperature resistance, vinyl fluorosilicone fluid remains stable in extreme temperatures ranging from -60°C to 250°C, and even after repeated thermal cycling, its physical property degradation rate remains below 5%. This characteristic makes it a core material for seals in spacecraft propulsion systems, capable of withstanding the transient high temperatures of fuel combustion and the ultra-low temperatures of space. Furthermore, the introduction of fluorine atoms imparts exceptional resistance to strong acids, bases, and organic solvents, making it widely used in anti-corrosion coatings for chemical equipment.
In the electronics industry, vinyl fluorosilicone fluid maintains a stable dielectric constant between 2.8 and 3.2, making it an ideal raw material for 5G base station antenna sealants. By adjusting the vinyl content, the curing speed and hardness of the material can be precisely controlled to meet the packaging requirements of different electronic components. With the development of the new energy industry, its application in lithium battery electrode coatings is also gradually increasing, effectively improving the battery's high-temperature resistance, safety, and cycle life.
