Halar is a flame- and impact-resistant plastic

Halar®(Ethylene-Chlorotrifluoroethylene)

  • Flame- and impact-resistant
  • Low permeability
  • Corrosion-resistant
  • Broad service use temperature range
 

Characteristics

This material is strong and highly impact-resistant. Halar® offers excellent electrical properties, low moisture absorption and temperature insensitivity. (Its use range spans from cryogenic to 300 degrees Fahrenheit.)

Virtually impervious to most common corrosive chemicals, Halar® also shows extremely low permeability to liquids, gases and vapors. This makes it a good choice for high-purity processing components for the chemical and semi-conductor industries.

Applications

  • Semiconductor process equipment
  • Chemical storage and fluid handling
  • Fire-safe components
  • Wire and cable insulation
