EURAFLON® – PTFE Products made by HECKER

HECKER uses the EURAFLON® brand name for its PTFE materials, and we only use raw materials from renowned PTFE manufacturers for its production.

EURAFLON is characterized by a number of special properties that no other plastic can match in this combination:

  • Excellent chemical resistance
  • Very wide temperature range (-200°C to 250°C)
  • Very low coefficient of friction; no stick-slip effect even with insufficient lubrication
  • Anti-adhesive surface
  • Non-flammable; however, contact with flames releases toxic fluorine gas
  • Excellent electrical insulation properties
  • Physically safe, weather-resistant, and does not absorb water

In addition to these mentioned properties, the following must be taken into account when designing:

  • High coefficient of expansion
  • Low thermal conductivity
  • Low abrasion resistance
  • Tendency to flow under load

The properties of PTFE can be tailored to a wide range of applications through the targeted addition of special fillers. PTFE compounds broaden the application range of PTFE and allow the material to be optimized for a specific purpose.

Applications

  • EURAFLON – PTFE Piston and Rod Seals
    Groove and lip seals, V-seal sets, PTFE-elastomer seal combinations (seal rings + O-rings), anti-extrusion rings (backup rings), wiper rings, and parts according to your drawings and samples

  • Seals for pipeline construction
    Flat gaskets, solid or coated, O-rings, glass flange gaskets, clamp flange gaskets, pipe fitting gaskets, bellows and expansion joints (also in vacuum versions), sealing cords and tapes.
  • Seals for rotation
    Radial shaft seals
  • Bearing elements
    Bushings, guide bands

    The packing is tailored to the specific application by impregnation with special compounds, such as lubricants for pump packings, binders, fillers, and dry lubricants for valve packings, or PTFE for piston pump packings.

PEREL® Special seals

The construction principle of the permanently elastic PEREL® Seal

The corrosion-resistant and permanently elastic gasket insert consists of PTFE-impregnated fiberglass fabric. The elastic properties of the three-dimensionally arranged fiberglass fibers create the elasticity of PEREL® gaskets.
