FVMQ Rubber | Flourosliocone Rubber | Seal & Design

FVMQ Flourosilicone       ASTM D 2000, SAE J200 Type/Class: FK

General Characteristics

Fluorosilicone rubber contains trifluoropropyl groups next to the methyl groups. The mechanical and physical properties are very similar to silicone rubber. However, fluorosilicone offers improved fuel and mineral oil resistance but poor hot air resistance when compared with silicone.

Temperature Properties

Heat Heat Resistance Up to 350°F (177°C).
Cold Cold Flexibility Down to approximately –100°F (–73°C).


Chemical Resistance Chemical Resistance
  • Aromatic mineral oils (IRM 903 oil)
  • Fuels
  • Low molecular weight aromatic hydrocarbons (benzene, toluene)
