The Graphite-Filled PTFE O-Ring is a premium sealing solution, engineered from PTFE resin enhanced with graphite for superior performance in challenging environments. This combination offers exceptional chemical resistance and excellent self-lubricating properties, making it a reliable choice for applications where low friction and durability are critical. The O-ring is ideal for use in high concentrations of hydrofluoric acid and volatile hazardous air pollutants (VHAP), making it a preferred option for industries such as chemical processing and oil and gas.

Key advantages:

  • Provides a lower coefficient of friction and reduces wear compared to other materials
  • Compatible with most hydraulic fluids, making it suitable for a wide range of industrial uses.
  • Graphite filler enhances the PTFE matrix to provide higher wear resistance
  • Graphite filler enhances thermal and electrical conductivity

Applications:

  • Chemical Processing: Ideal for sealing in systems handling highly concentrated hydrofluoric acid and other corrosive substances.
  • Environmental Control: Suitable for applications involving volatile hazardous air pollutants (VHAP).
  • Industrial Gaskets: Available in various sizes and thicknesses, perfect for custom die-cut gaskets in critical sealing applications.

Frequently Asked Questions

Of course, we can customize pfe products to your satisfaction according to your material, size and process

The maximum size of ptfe molded plate can reach 2000mm long * 2000mm wide * 390mm thick,
ptfe rods have a maximum length of 4000mm and a diameter of 500mm

PTFE is essentially chemically inert and is highly resistant to chemical attack up to its 500º F. maximum continuous operating temperature. As indicated in the referenced PTFE Handbook above, there are a few exceptions including molten alkali metals, turbulent liquid, or gaseous fluorine; and a few fluorochemicals, such as chlorine trifluoride, ClF3, or oxygen difluoride, OF2, which readily liberate free fluorine at elevated temperatures.  Several tables are available on the web supporting appropriate usage of PTFE with chemicals and various concentrations and temperatures. 

We have a set of strict quality testing system, never expected finished products, will be tested and registered, traceable

The general production cycle of ptfe products is about 15 days, and the delivery date can be agreed on for customized products
