Permeaflon® porous PTFE

PTFE supplemented with porous properties

Berghof complements the unique properties of polytetrafluoroethylene (PTFE / Teflon®) to a porous structure and opens up with the development of customized solutions and new versatile fields of application in the field of porous materials.

Outstanding properties
  • Symmetrical porous structure (no preferred direction)
  • Operating temperature range: -250 to +260°C
  • Universal chemical resistance
  • Minimal surface tension (anti-adhesive surface and extremely low friction coefficient)
  • Extremely hydrophobic (no water absorption)
  • Excellent (di)electric properties
  • High UV and weather resistance
  • High flame resistance
  • Physiologically non-hazardous
  • Free from perfluorooctanoic acid (PFOA)
Manufacturing process

Thanks to the use of specially developed starting granules and production processes, Berghof is able to add porous properties to products made from the high-performance plastic polytetrafluoroethylene (PTFE). Developed and perfected by Berghof, the isostatic pressing process also comes to the fore during production of porous PTFE products. This allows components with demanding geometrical shapes to be manufactured with the highest quality materials, maximum homogeneity and minimal use of resources. During manufacturing, Berghof's porous PTFE is subjected to a sintering process at over 300°C. This gives the products high temperature and dimensional stability. Thus, even the most demanding challenges can be met through the use of permeaflon®.
