In industries such as automotive, petrochemicals, and high-performance sealing, materials must withstand long-term exposure to oils, solvents, and high-temperature environments. Vinyl fluorosilicone oil—an advanced reactive fluorinated silicone fluid—offers a unique combination of media resistance and crosslinking capability, making it an essential component in modern fluorosilicone rubber systems.

Its molecular structure features trifluoropropyl side chains, providing superior resistance to polar solvents, oils, and extreme temperatures. The terminal vinyl groups enable efficient crosslinking through addition or radical reactions. Most commonly, it reacts with hydrogen silicone oils (e.g., methylhydrogensiloxane) under platinum catalysis to form durable, flexible fluorosilicone elastomers.

Vinyl fluorosilicone oil is widely used in manufacturing high-performance O-rings, oil-resistant hoses, chemical-resistant gaskets, and aerospace fuel system components. It significantly enhances rubber products’ volume stability and mechanical properties in contact with fuels, esters, ketones, and aggressive chemicals, reducing maintenance needs and extending service life.

As new-energy vehicles, special-purpose equipment, and hydrogen-related technologies advance, demand grows for materials with enhanced chemical resistance and thermal flexibility. Vinyl fluorosilicone oil is expanding its applications to electronic seals, sensor encapsulation, and battery protective coatings, supporting next-generation innovation in harsh operating environments.
