3M™ Dyneon™ Low Temperature Fluoroelastomer LTFE 6400Z, 25KG/55LB BX
Dyneon™ LTFE is a technically advanced elastomer offering a unique dynamic sealing capability at low temperatures as well as the broad chemical resistance that is expected from a fluoroelastomer. Dyneon™ LTFE 6400 Z is now approved to AMS Aerospace Materials Specification 7379 (-40°C fluorocarbon elastomer (FKM)).
  • TR10 = -40°C which means true dynamic sealing capability at low temperatures.
  • Very good chemical resistance against most chemicals such as acids, bases, fuels, oils, coolants, and alcohols.
  • Processes comparably to other peroxide-cured fluoroelastomers.
  • Good compression set resistance with low/no post-cure.
