It is a partially fluorinated semi-crystalline polymer offering a unique combination of properties for highly demanding industries. It is widely used in anti-corrosion applications as a lining or in self-supporting constructions (piping). Its excellent fire resistance properties and chemical resistance make it a first choice in wire and cable applications. It offers purity, surface smoothness, chemical resistance and fire resistance which are key characteristics in the semiconductor and photovoltaic markets.Key Features:

  • Low permeability
  • Excellent weatherability
  • High purity
  • Excellent release properties
  • Good abrasion resistance
  • This material data has been provided by M-Base.
