Special Features

  • TR10 = -40 °C, which means true dynamic sealing capability at low temperatures
  • Processes comparable to other peroxide-cured fluoroelastomers

  • Very good chemical resistance against most chemicals such as acids, bases, fuels, oils, coolants, and alcohols
  • Good compression set resistance

Typical Applications

Dyneon LTFE 6400Z can be used for manufacturing parts such as O-rings and fuel injectors, among others.
