PTFE O ring cord Features

  • Extreme temperature resistance – suitable for continuous use from -180°C to +260°C, and can withstand short-term peaks up to 300°C.

  • Low friction & self-lubricating – minimizes wear and enhances mechanical efficiency.
  • Superior electrical insulation – stable dielectric properties across temperature and frequency
  • Durable and safe – non-toxic, chemically stable, and ideal for food and pharmaceutical industries.
  • Chemical resistance – withstands strong acids, alkalis, water, and a wide range of organic solvents.
