Evolution of Seal Materials

The evolution of seal materials evolved as seals faced more rugged demands.  Early needs could be met using packed hemp or leather, but as the demands became more and more rigorous new materials were sought.  This led to the introduction of natural rubber seals, which evolved into synthetic elastomers, and finally engineering polymers like PTFE (Polytetrafluoroethylene).

Four of the most common modern material options for rotary shaft seal lips are nitrile rubber, polyacrylate, FKM, and PTFE.  Of these materials, three are elastomers – nitrile rubber, polyacrylate rubber and FKM – and only one is polymer – PTFE.  Let’s see how these materials stack up.

Where High-Speed Seals Are Found

High speed rotary shaft seals are found in many applications.  Examples would include cryogenic deflashing equipment, vacuum pumps, torpedo shaft seals, gas turbine engine starters, and submersible dredge pumps.  AC/DC motors often require high speed shaft seals, and can be found in items like CNC tool spindles and dental or surgical instruments.
