Fluorosilicone Rubber Sheet and Uncured Compound
ElastaPro manufactures high‑performance fluorosilicone (FVMQ) engineered for environments where standard silicone is not enough — especially in the presence of fuels, oils, solvents, and aggressive chemicals. Our fluorosilicone sheet and uncured compound deliver the temperature stability of silicone with the fuel resistance of fluorocarbon elastomers, making them ideal for aerospace, defense, automotive, and industrial sealing applications.
Whether you need fluorosilicone sheet, AMS/MIL‑spec materials, or custom‑formulated FVMQ compounds, ElastaPro provides U.S.‑made, tightly controlled, high‑purity materials with fast lead times.
What Is Fluorosilicone Rubber (FVMQ)?
Fluorosilicone is a fluorinated silicone elastomer that combines:
- The flexibility and temperature range of silicone
- The fuel, oil, and solvent resistance of fluorocarbon elastomers
This makes FVMQ the material of choice for sealing applications exposed to:
- Jet fuels (JP‑8, Jet‑A, Jet‑A1)
- Aviation gasoline
- Diesel and biodiesel
- Aromatic and aliphatic hydrocarbons
- Synthetic lubricants
- Solvents and chemical vapors
Fluorosilicone maintains elasticity and sealing performance where standard silicone swells, softens, or breaks down.
Key Advantages of Fluorosilicone
Outstanding Fuel & Oil Resistance
Performs reliably in aviation fuels, automotive fuels, solvents, and petroleum‑based fluids.
Wide Temperature Range
Typical service range of −60°C to +200°C (−76°F to +392°F), depending on formulation.
Excellent Long‑Term Stability
Resists:
- Thermal cycling
- UV and ozone
- Weathering
- Compression set
Superior Chemical Compatibility
Ideal for environments where silicone, EPDM, nitrile, and neoprene fail.
Available in Multiple Durometers
Common hardness options: 40, 50, 60, 70, 75, and 80 Shore A
Spec Grade Materials
Spec-grade fluorosilicones from ElastaPro meet AMSR25988 (formerly MIL-DTL-25988) requirements and/or AMS specifications.

Fluorosilicone Compound (Uncured FVMQ)
For molding, extrusion, or custom fabrication, ElastaPro supplies uncured fluorosilicone compound with:
- Controlled rheology
- Excellent mold flow
- High tear strength
- Consistent cure characteristics
Available in peroxide‑cured or platinum‑cured systems.
Industries That Rely on Fluorosilicone
Fluorosilicone is widely used in:
- Aerospace & Defense
Fuel system seals, O‑rings, gaskets, environmental seals - Automotive & Transportation
Fuel vapor systems, turbocharger seals, under‑hood components - Industrial & Chemical Processing
Solvent‑exposed gaskets, chemical transfer systems - Energy & Power Systems
Fuel cell components, chemical‑resistant insulation
Its unique combination of chemical resistance + temperature stability makes it indispensable in mission‑critical environments.
Fluorosilicone vs. Silicone vs. Viton (FKM)
| Property | Fluorosilicone (FVMQ) | Silicone (VMQ) | Viton (FKM) |
| Fuel Resistance | Excellent | Poor | Excellent |
| Temperature Range | Excellent | Excellent | Good |
| Flexibility at Low Temps | Excellent | Excellent | Moderate |
| Chemical Resistance | High | Moderate | Very High |
| Cost | Higher | Moderate | Higher |
Bottom line:
Fluorosilicone is the best choice when you need silicone‑like flexibility with fuel and solvent resistance.
