Applications in high-end sealing, aerospace, fuel systems, and precision electronics are placing higher demands on silicone materials for oil resistance, high and low temperature resistance, and structural adjustability. As a representative product among functional fluorosilicone fluids, vinyl fluorosilicone fluid, with its active vinyl structure and trifluoropropyl side chains, has become a key intermediate in the preparation of copolymerized fluorosilicone rubber.
The basic structure of vinyl fluorosilicone oil consists of a main-chain siloxane backbone with trifluoropropyl groups introduced into the side chains and vinyl functional groups at the ends. This molecular design not only imparts excellent chemical inertness and low surface energy to the material, but also possesses strong reactivity, allowing it to undergo addition reactions with hydrogen-containing silicone oils under platinum catalysis, thereby constructing a multifunctional cross-linked network. This copolymerization technology is widely used to prepare fluorosilicone elastomer composites that are highly transparent, oil-resistant, solvent-resistant, and resistant to high and low temperatures.
On the application side, vinyl fluorosilicone fluids are primarily used in synthetic aviation engine fuel system seals, oxygenated fuel valve gaskets, automotive sensor shields, electronic potting seals, and other demanding products. They also demonstrate strong adaptability in specialty coatings, lubricating films, and corrosion-resistant protective layers.
This material also offers excellent compatibility and molecular design flexibility, allowing for personalized customization of viscosity, functionality, and fluorine content based on product processing, meeting diverse performance requirements from soft gels to high-strength rubbers. With the continued development of fluorosilicone materials in new energy, military, aviation, and rail transportation, vinyl fluorosilicone oil will play an increasingly important role as a foundational structural oil.
