We can design the tubes you need for your hydrogen system

  • Polytetraflon™ PTFE tubes and Moldflon™ thermoplastic tubes can be used in hydrogen systems.
  • Tubes made from high performance plastics offer a broad range of application possibilities due to their exceptional  chemical, thermal and dielectric properties.
  • Heat shrinkable tubing made from high performance plastics offer a safe protection against moisture, chemical liquids, corrosion and high temperatures.

Our materials

  • Polytetraflon™-PTFE
  • Moldflon™-PTFE
  • Moldflon™-PFA, -FEP, -PEEK, -PEI, -ETFE and –PVDF

Key benefits of our products

  • Our tubes are suitable for a broad spectrum of high end applications thanks to their unique application specific properties
  • Excellent thermal and chemical resistance
  • Outstanding friction properties
  • Anti-adhesive
  • Good electrical insulation properties
  • Physiologically harmless
  • Autoclavable

Polytetraflon™-PTFE

  • Lowest friction coefficient of any polymer
  • Exceptionally large operating temperate range: -260°C to +260°C
  • Very good sliding characteristics – self-lubricating effect
  • No water absorption, water repellent
  • Anti-adhesive
  • Almost universal chemical resistance
  • Good electrical and dielectric properties
  • Resistance to superheated steam
  • Light, weather and UV radiation resistant
  • self extinguishing in acc. with UL 94 V-0
  • Physiologically harmless

Moldflon™-PTFE

  • In contrast to conventional PTFE, Moldflon™ can be processed thermoplastically by means of injection molding and extrusion (particularly attractive for large-scale production)
  • Significant better wear behavior than Polytetraflon™- PTFE and modified PTFE

Application areas

  • Media transport in alkaline electrolysers and pressureless water electrolysis
  • Components for electrical and electronic applications
  • Protective sheath against moisture, chemical liquids, corrosion and high temperatures
  • Our PTFE-tubes offer a broad range of application possibilities due to their exceptional  chemical, thermal and dielectric properties. Thanks to this, Polytetraflon™-PTFE tubes are increasingly used e.g. in chemical, electrical and mechanical industries
