Excellent- 10 to 100 times better than those of PTFE or FEP to oxygen, carbon dioxide, chlorine gas, or hydrochloric acid.
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.
Similar to Nylon 6
Halar® is UL certified for use in non-load bearing applications requiring continuous service at temperatures to 150°C (300°F).
Less than 0.1%.
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.
Resists a wide variety of corrosive chemicals and organic solvents, including strong acids, chlorine, and aqueous caustics.
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.
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.
Halar® is not wetted by water, but oil and hydrocarbons readily spread on its surface.
