The Application Case of the Fluorosilicone Gum

Fluorosilicone Gum (FVMQ raw gum) serves as the premium base polymer for high-performance fluorosilicone compounds. It is widely used to formulate molded and extruded parts for automotive fuel systems, including O-rings, gaskets, diaphragms and fuel-line components, offering excellent resistance to gasoline, diesel and oil.

In aerospace and aviation, it provides stable sealing at extreme temperatures (-65℃ to 230℃) for engine and hydraulic systems. For EV and new energy applications, it ensures safe insulation and chemical resistance in battery and powertrain components.

It is also ideal for industrial seals, wire insulation, and military-grade parts requiring long-term aging, ozone and UV resistance. With excellent processability and consistent quality, it supports reliable mass production of high-performance FVMQ products worldwide.

The Production Process of Fluorosilicone Gum

Fluorosilicone Gum is produced via anionic ring-opening polymerization of trifluoropropylmethylcyclotrisiloxane (F3) monomer under strict anhydrous conditions. Purified monomer is polymerized at controlled temperature with an alkali catalyst, forming high-molecular-weight linear fluorosilicone chains. Vinyl groups are introduced for crosslinking. The process includes neutralization, devolatilization, and filtration to remove residuals and low molecular weight fractions. Final stabilization ensures consistent molecular weight, low volatiles, and excellent processability. The closed-loop system guarantees high purity, uniform structure, and batch-to-batch stability for high-performance FVMQ applications.
