About PTFE Coating on Magnets

  • Requires molds and tooling
  • Excellent protection to magnet against breakage, impact, and corrosion
  • Available on magnets that are medium to larger in size. Small magnets cannot be molded, but can be sprayed (see Spray PTFE – Teflon)
  • Provides a protective coating from humidity, fluids and AutoClave
  • Color of PTFE is white
  • Thickness: 0.5-1 mm
  • Max working Temp: Approximately 250o C
  • Gluing PTFE magnets onto steel or plastic has very poor adhesion. A mechanical hold is recommended

    About Large Neo Disc Magnets

    Our Large Neodymium Disc Magnets are defined as a neodymium magnet with a diameter > or = 1.000" (25.40mm).  The diameter of a round neodymium magnet has a direct impact on the holding force, pull force, and magnetic field profile.  Large round disc magnets are very strong and can be harmful if not handled carefully and cautiously.  

    View our  Magnet Crashes Video  for tips on safe handling.  

    Large Disc Magnets are predominately used as sensor magnets, motor magnets, medical magnets, consumer electronics magnets, and holding magnets.
