ePTFE-packing made from expanding PTFE with incorporated white filler, with silicone oil as lubricant

  • Article Number: 1737
  • Material: 1737
  • Profile: PG/PR
1737
  • No colour contamination of media due to abrasion.
  • Packing complies with FDA requirements for use as sealing material in food industry.
  • In comparison to pure PTFE lower heat strain and higher heat conductivity, hence longer service life and more shaft-friendly.
  • High chemical resistance, similar to pure PTFE. Incorporated white filler is also resistant against oxidising acting acids, therefore can be used instead of formerly used blue asbestos-acid packings.
