Neodymium Teflon Coated Magnet

Introduction to Teflon-Coated Magnets

Polytetrafluoroethylene, better known as PTFE or Teflon®, is a synthetic fluoropolymer discovered by Roy Plunkett. He was researching new refrigerants and trying to find a non-toxic substitute for sulfur dioxide and ammonia at DuPont. Teflon is a fluorocarbon-based polymer with multiple strong carbon-fluorine bonds, making it highly resistant to various substances. As a type of non-stick coating, Teflon is widely known for its use in pans and other cookware. Additionally, Teflon coating can also be applied to containers and pipework for reactive or corrosive chemicals due to the strength of carbon-fluorine bonds. Consequently, Teflon-coated magnets are utilized in certain specialized applications.

Advantages of Neodymium Teflon-Coated Magnets:

1. Non-stick performance.
2. Teflon-coated magnets have a low friction coefficient, less than 0.1, second only to diamond.
3. Excellent water resistance.
4. Outstanding temperature stability allows Teflon coating to function continuously under both high and low temperature conditions. The maximum operating temperature can reach 260°C.
5. Non-conductive.
6. Teflon-coated sintered Neodymium magnets have excellent chemical resistance, enabling them to operate steadily in acidic or alkaline environments when free of pinholes.
