Viton™ AL-Type Fluoroelastomers

Improved Processing with Viton™ AL-Type Fluoroelastomers

Viton™ AL-type fluoroelastomers are gum terpolymers comprised of hexafluoropropylene (HFP), vinylidene fluoride (VF₂), and tetrafluoroethylene (TFE). They are ideal for applications where resistance to compression set and the ability to return to original thickness after a compression load has been applied are essential.

The Viton™ AL family of products is widely used in fuel systems, including:

  • Fuel injector O-rings
  • Injection and transfer molding of O-rings, gaskets, and other sealing devices
  • Extruded cords, profiles, and tubing
  • Solution coatings of fabrics and other substrates

Features and Benefits

The "L" designation in Viton™ AL indicates that the polymer provides slightly improved low-temperature flexibility characteristics versus other polymers within the same family.

Viton™ AL-type fluoroelastomers offer:

  • Improved mold flow
  • Better mold release
  • Less mold fouling
  • Improved compression set resistance
  • Good low temperature characteristics
