Dynaflon® O-rings

In continuous processes or in corrosive media you need extremely reliable components to avoid production failures. That is why Vaneflon has been manufacturing Dynaflon® PTFE-encapsulated Viton seals for more than 25 years. They combine the chemical resistance of PTFE with the sealing performance of Viton. Their higher elasticity avoids problems with leakages or at assembly, compared to virgin seals and allows you to save costs in the long run.

Dynaflon® offers superior tensile strength, elongation and folding endurance, as well as a low friction coefficient and high maximal temperature capabilities. The Dynaflon® O-ring (Kamlock, D-shaped, Orings …) brings added value over FEP or PFA encapsulated O-rings, especially for customers who have issues with the lifetime or re-use of their O-rings. Where FFKM O-rings are a very high cost alternative, Dynaflon® O-rings can provide the right solution with the following benefits:

Key properties

  • Superior chemical resistance
  • Superior tensile strength
  • Superior elongation
  • Lower coefficient of friction
  • Superior folding endurance
  • Higher maximum temperature capability (higher melting temperature than FEP)
  • Superior than solid PTFE O-rings that have issues during assembly of leakage because of the lack of elasticity
  • Very low coefficient of friction (6 x lower than FEP-PFA)
  • Very low permeability
  • Homogeneous surface
  • Available in standard DIN and ANSI dimensions
  • Cost-saving

Applications

  • Vacuum applications
  • Low contamination applications
  • High temperature operations
  • UHV-pressure applications
