FLUOROPOLYMER RESIN
Processability – HALAR® fluoropolymer can easily be processed by injection molding, compression molding, blow molding, extrusion, rotomolding, and electrostatic spray and fluidized bed coating techniques.
Thermal Properties – The continuous thermal rating for HALAR® fluoropolymer is 300°F to 350ºF depending on resin grade. The thermal capability of the material can be extended to 400ºF by radiation cross-linking.
Chemical Resistance – HALAR® fluoropolymer is resistant to a wide variety of corrosive chemicals and organic solvents, including strong acids, chlorine and aqueous caustic. No known solvent dissolves or stress cracks the polymer at temperatures up to 250ºF.
Electrical Properties – The dielectric constant of HALAR® fluoropolymer is low (2.6 for solid insulation to 1.5 for foamed insulation) and stable across a broad temperature and frequency range. The dielectric strength is 2000 volts/mil in 1 mil thickness.
Toughness and Strength – HALAR® fluoropolymer possesses excellent mechanical properties over a wide range of temperatures from cryogenic temperatures to 340ºF. It has nylon-like durability and provides excellent impact resistance at ambient and subambient temperatures.
SUGGESTED INDUSTRY USES

Weldability – HALAR® fluoropolymer is weldable with ordinary thermoplastic welding equipment at 480°F-500ºF.
Barrier Properties – Barrier properties of HALAR® fluoropolmmer are excellent – 10 to 100 times better than those of PTFE or FEP to oxygen, carbon dioxide, chlorine gas or hydrochloric acid.
Radiation Resistance – HALAR® fluoropolymer maintains useful properties on exposure to cobalt 60 radiation of 200 megarads.
Flammability – HALAR® fluoropolymer, in thickness as low as 7 mil, has received a UL 94 V-O rating. The oxygen index (ASTM-D-2863) of HALAR® fluoropolymer is 60 on a 1/16” thick specimen and 48 for .0005 inch diameter filament yarn.
Weatherability – No change after 3000+ hours exposure in a Zenon arc weatherometer.
Machinability – Similar to nylon 6.
Water Absorption – Less than 0.1%
