In specialized industrial scenarios such as petrochemical processing and automotive fuel systems—where prolonged contact with non-polar solvents is common—conventional liquid silicone rubber tends to swell and degrade upon exposure to oils. The development of fluorine-modified fluorosilicone rubber products has specifically filled this application gap, providing a reliable silicone-based material solution for demanding operating conditions.

Conventional liquid silicone rubber, lacking fluorine atoms in its molecular structure, experiences gradual permeation of solvent molecules between its polymer chains when exposed to engine oils, diesel fuels, and aromatic hydrocarbons over extended periods. This leads to significant volumetric swelling, substantial reduction in mechanical strength and sealing performance, ultimately rendering the material unable to meet service requirements. In contrast, fluorine-modified fluorosilicone rubber introduces fluorinated groups onto the side chains of the molecular backbone, greatly enhancing the material's resistance to non-polar solvents. Even under prolonged immersion in media such as engine oil and diesel, the volumetric change rate can be controlled to extremely low levels, while mechanical properties remain stable.

In addition to its excellent oil and solvent resistance, fluorosilicone rubber retains the inherent broad-temperature-range stability of silicone materials. It maintains elasticity across a wide spectrum from low to high temperatures, without becoming hard or brittle due to drastic environmental temperature fluctuations. Furthermore, the material's resistance to acid and alkali corrosion has been further enhanced, enabling it to maintain long-term protective performance even when exposed to certain mildly corrosive industrial chemicals.

Currently, this fluorine-modified liquid silicone rubber has achieved batch-scale application in petrochemical equipment sealing, automotive fuel system components, and specialized industrial anti-corrosion coatings, addressing numerous operating condition challenges that conventional silicone rubber materials could not accommodate. It offers a new, highly reliable option for material selection in specialized industrial environments, further expanding the application boundaries of silicone rubber materials.
