Cathay™PFA films are highly chemically inert and solvent resistant; have low permeability to liquids, gases, moisture, and organic vapors; and exhibit very good dielectric properties, high continuous service temperature, favorable antistick and low frictional properties, as well as good weathering and optical properties. Additional features of PFA films are superior creep resistance at high temperatures, excellent low-temperature toughness, and exceptional flame resistance.
These films offer the highest continuous use temperature of 260°C (500°F) of any melt-processable fluoropolymer film type. They offer many of the performance properties of PTFE films in a clear, transparent form.
Typical applications of Cathay™ PFA films are in chemical processing, wire and cable, electronics, mold release in processing composites, circuit board laminates, chemical pumps, tank linings, shrink roll covers, and rupture discs and gaskets.
