Halar® Properties
Barrier Properties
Excellent- 10 to 100 times better than those of PTFE or FEP to oxygen, carbon dioxide, chlorine gas, or hydrochloric acid.
Electrical Properties
The dielectric constant of Halar® is low and stable across a broad temperature and frequency range. The dielectric strength is 80 kV/mm (2000 V/mil) in .025 mm (1mil) thickness.
Machinability
Similar to Nylon 6
Thermal Properties
Halar® is UL certified for use in non-load bearing applications requiring continuous service at temperatures to 150°C (300°F).
Water Absorption
Less than 0.1%.
Surface Smoothness
Halar® is distinguished from all other fluoropolymers by its exceptional surface smoothness. Halar® exhibits extraordinary smoothness as measured by SEM and AFM analytical methods. A very important benefit of this surface property was demonstrated in biofilm testing. The formation of biorganic films and bacterial colonies was significantly reduced on process surfaces of Halar® versus electropolished stainless steel and PVDF.
Chemical Resistance
Resists a wide variety of corrosive chemicals and organic solvents, including strong acids, chlorine, and aqueous caustics.
Mechanical Properties
Halar® possesses excellent mechanical properties over a wide range of temperatures from cryogenic to 150°C (300°F). It has Nylon-like durability and provides excellent impact resistance at ambient and sub-ambient temperatures. Halar® has good tensile, flexural, and wear-related properties.
Purity
Static soak testing in Ultra-Pure Water and High Purity Chemicals show extremely low levels of metallic and organic extractables. Additional dynamic rinse data also validates Halar® as a material suitable for high purity systems in the semiconductor, biotech, and pharmaceutical industries.
Hydrophobic
Halar® is not wetted by water, but oil and hydrocarbons readily spread on its surface.

Chemical Resistance
Halar® fluoropolymer exhibits outstanding chemical resistance and excellent barrier properties. It is virtually unaffected by most corrosive chemicals commonly encountered in industry.
Among those substances that Halar® fluoropolymer is resistant to are strong mineral and oxidizing acids, alkalis, metal etchants, liquid oxygen and essentially all organic solvents except hot amines (e.g. aniline, dimethylamine).
Typical of fluoropolymers, Halar® is attacked by metallic sodium and potassium. Rate of attack is function of exposure time and temperature.
Halar® and other fluoropolymers can become slightly plasticized by contact with certain halogenated solvents, but this effect does not normally impair its usefulness. After contact ceases and the part is allowed to dry, the mechanical properties return to their original value, indicating that no chemical attack has occurred.
Halar® fluoropolymer is compatible with liquid oxygen (LOX) as measured by the National Aeronautics and Space Administration test MSFC-SPEC-106B. It is resistant to nitrogen tetroxide (NTO) and monomethylhydrazine (MMH).
Mechanical Properties
Halar® fluoropolymer is a strong, highly impact-resistant material that retains its useful properties over a broad range of temperatures. Its low-temperature properties, especially those related to impact, are particularly outstanding. Information on the important mechanical properties is provided in the accompanying table. In addition to excellent impact properties, Halar® fluoropolymer is seen to have good tensile, flexural and wear-related properties.
- Tup A per ASTM D2444, 4 in. diameter disc supported on 3 in. I.D. ring.
- CS-17 wheels; 500 gram load; abrasion wheels cleaned after every 25 cycles.
- 30-pound load.
