Material Composition & Key Properties

● Structure Origin: PTFE is synthesized from tetrafluoroethylene (TFE) monomers via free-radical polymerization, resulting in a linear chain of –CF₂– units.
● Processing Techniques: Common methods include suspension polymerization for granular products, or emulsion polymerization for fine powders and coatings.
● Key Properties:

  • Extremely high chemical resistance
  • Excellent thermal stability (up to 260°C continuous)
  • Low coefficient of friction (non-stick)
  • Exceptional dielectric strength
  • Biocompatible and non-toxic
  • Resistant to UV, weathering, and moisture

These traits make PTFE ideal for high-performance applications in harsh, corrosive, or sterile environments.
