Arctic-Grade Fuel Resistant FVMQ (Fluorosilicone) BDFS Series
Overview
BDFS Series: -60°C Arctic-Grade FVMQ with Superior Fuel & Oil Resistance
The BDFS Series (Arctic-Grade Fluorosilicone) is a high-performance FVMQ elastomer engineered to provide a dual-shield against extreme thermal stress and aggressive chemical media. Combining the extraordinary low-temperature flexibility of silicone (-60°C) with the superior gasoline and oil resistance of fluoroelastomers (FKM), the BDFS series is the definitive choice for critical seals in aerospace, automotive, and polar industrial applications. These compositions cure to form high-strength moldings that exhibit minimal volume swell when exposed to fuels, hydrocarbon solvents, and engine oils, while maintaining mechanical elasticity across a massive temperature window from -60°C to +200°C. Whether for high-altitude aerospace fuel lines or Arctic-grade automotive gaskets, the BDFS series delivers the reliability needed where standard elastomers fail.
-
Extreme Cold Flexibility
Maintains its sealing force and elastic memory in temperatures as low as -60°C, preventing leaks during cold-start or high-altitude operations.
-
Superior Fuel & Oil Barrier
Provides an exceptional barrier against Gasoline, Jet Fuel (JP-8), Diesel, and Silicone-based oils, outperforming standard silicones in volume swell resistance.
-
Thermal Range Versatility
Operates reliably from -60°C to +200°C, offering a stable performance profile that is unmatched by copolymers or standard terpolymers.
-
Outstanding Weatherability
Highly resistant to Ozone, UV radiation, and outdoor aging, ensuring a long service life for external aircraft and vehicle components.
-
Excellent Processability
Optimized for precision molding and extrusion, with superior mold release and flow properties that result in low scrap rates and high-definition details.
Material & Manufacturing Technology
- Molecular Hybridization: Formulated with a polysiloxane backbone containing trifluoropropyl groups, effectively marrying the wide-range temperature stability of silicone with the chemical inertness of fluorine.
- Cleanroom Compounding: Produced in high-purity environments to ensure the material is free from contaminants that could affect the delicate balance of its cold-weather properties.
- Cross-linking System: Typically peroxide-cured to provide a robust, high-tear-strength molecular network suitable for dynamic and static sealing.
Solutions & Application Scenarios
- Aerospace Fuel Systems: Diaphragms, O-rings, and gaskets for Jet Fuel (JP-8) lines that undergo rapid thermal cycling during high-altitude flights.
- Automotive Turbochargers: Turbocharger hoses, intercooler seals, and engine bay gaskets exposed to high heat and oil vapor.
- Arctic Oil & Gas: Sealing components for pipelines, valves, and drilling equipment operating in Siberian or Arctic offshore
- Defense & Military: Critical seals for cold-weather military vehicles and equipment requiring instant readiness in sub-zero terrains.
Why BDFS Series FVMQ? (The Performance Solution)
- Eliminating the Compromise: Standard Silicone swells in fuel; standard FKM freezes in the cold. BDFS Series eliminates this compromise, providing a single-material solution.
- High-Precision Sealing: The excellent flow properties allow for the production of ultra-thin diaphragms and micro O-rings used in precision fuel injection and sensing equipment.
- Durability in Static & Dynamic Use: Whether as a stationary flange gasket or a moving valve seal, the BDFS series maintains its structural integrity under constant pressure.
