Operating Temperature-65°C to +175°C
Fluorosilicone (FVMQ — Fluorovinylmethyl Silicone) uniquely combines the excellent low-temperature flexibility of standard silicone with resistance to fuels, oils and solvents. This makes it particularly valuable in aerospace and automotive fuel system applications where both extremes must be handled.
Key Properties
- Exceptional low-temperature flexibility down to -65°C
- Resistant to fuels, oils and solvents — unlike standard silicone
- Good heat resistance up to 175°C
- Good ozone and UV resistance
- Low compression set
Limitations
- Not for high-pressure dynamic sealing applications
- Poor abrasion resistance
- Higher cost than standard silicone
Typical Hardness
50–80 Shore A available
Typical Applications
- Aerospace fuel systems and jet engines
- Automotive fuel injection and carburettors
- Military equipment operating in extreme climates
- Cryogenic fluid handling
- Avionics and instrument seals
