HALAR (ECTFE)

GEHR HALAR (ECTFE)®

Halar exhibits an extraordinary impact strength at temperatures ranging from -104 °F to +302 °F. A great part of the product properties attributes to the very smooth surface and differentiates Halar® from other fluoropolymers. Due to the fact that Halar is very pure, this material is being used to process chemicals and ultrapure water for the semiconductor industry.
Also the permeation resistance to oxygen, carbon dioxide, chlorine gas and hydrochlorid acid is 10 to 100 times better than PTFE.

Properties:

  • extremely high impact strength (up to -105 °F)
  • good insulation properties
  • very good weather resistance
  • high resistance to radiation
  • very high chemical resistance
  • self-extinguishing
  • very good sliding properties
  • physiologically harmless
  • food safe
  • high density
  • limited protection against stress cracking at temperatures > 284 °F
  • very low moisture absorbtion at < 0.1%

Applications:

Parts which come in contact with aggressive materials (machine-building industry), lining of tanks, pumps, flanges, fittings, parts in centrifuges and control engineering industry, valves seats and valve seals.
