Product information "thoenes ® PTFE flat sealing material"

thoes ® PTFE flat sealing materials consist of pure, virgin PTFE and contain no additional reinforcements or fillers. Our PTFE flat sealing materials are harmless to health, have excellent chemical resistance, adapt well and have low friction. Depending on the application, these materials are available in FDA-grade quality.

Key properties :

  • Good electrical properties,
  • Non-stick effect due to a very low coefficient of friction,
  • Very good weather resistance,
  • No ageing,
  • Continuous operating temperature is 250 °C; short-term temperatures of up to 260 °C are possible.

Areas of application :

PTFE seals are used in chemical plant engineering for corrosion protection and as sealing material. In mechanical and automotive engineering, their excellent sliding properties are utilised for self-lubricating bearings, sliding elements and seals. They are also used in the electronics sector, in electrical engineering, as well as in aerospace and data processing.
