Halar ECTFE is a partially fluorinated semi-crystalline polymer offering a unique combination of mechanical properties, thermal and chemical resistance with an outstanding ease of processability. Halar ECTFE, a copolymer of ethylene and chlorotrifluoroethylene, can bring advantages to the end user when compared to other fluoropolymers. It is a very versatile polymer, available in all forms to meet processing needs. Halar offers excellent resistance to abrasion, harsh chemicals, and permeation. For those applications exceeding the capabilities of PVDF, Halar can be evaluated before resorting to a fully fluorinated polymer, offering a compromise between the mechanical properties of a partially fluorinated plastic like PVDF and the chemical and thermal resistance which is typical of totally fluorinated polymers. These characteristics have made of Halar ECTFE a material of choice for several applications in the field of corrosion protection in the chemical, pharmaceutical and microelectronic industry. The excellent processability, together with the electrical properties, has allowed Halar to become an ideal solution for wire and cable insulation. Halar ECTFE is a high purity fluoropolymer with a very smooth surface, which accounts for its extensive use in the semiconductor industry. Halar meets the demands for fire-safe, non-fire propagating plastics. Halar ECTFE powder coatings offer the greatest ease of processing, with the ability to be applied in high thickness when required. Since 1990, Halar ECTFE powder coatings have been used successfully for corrosion protection of exhaust duct systems that must meet the FM 4922 fire safety standard. In addition, Halar plastic sheet is used to meet FM4910 and UL2360 standards for fabrication of fire safe cleanroom tools. Halar powder coatings have replaced PVDF sheet linings in ultrapure water (UPW) systems.
