Fluorosilicone

Fluorosilicone is a synthetic elastomer that combines the temperature resistance of silicone with the chemical resistance of fluorocarbon. It is commonly used in applications that require resistance to fuels, oils, and solvents over a wide temperature range. Fluorosilicone is known for its excellent performance in extreme environments, particularly in aerospace and automotive applications.

Fluorosilicone Recommended Uses

  • Aerospace seals and gaskets
  • Fuel systems
  • Automotive components
  • Military and defense applications
  • Industrial equipment
  • Chemical processing
  • Oil and gas industry

Fluorosilicone Not Recommended

  • ketones
  • acids
  • amines
  • hydrocarbon fuels
  • phosphate esters
  • silicone fluids
  • steam
  • ozone
  • UV exposure

Fluorosilicone Limitations

  • Lower mechanical strength compared to other elastomers
  • Not suitable for continuous exposure to high temperatures beyond 200°C
  • Limited abrasion resistance
  • Not ideal for steam or highly dynamic applications
  • May swell in certain solvents
  • Not recommended for applications requiring low compression set
  • May require special handling due to its chemical resistance
  • May require post-curing for optimal performance

Fluorosilicone Usable Temperature Range

-60°C to 200°C

Fluorosilicone also known as:

Fluorosilicone, FVMQ, Fluorosilicone Rubber
