VICTREX® APTIV® 1000 PEEK Film

VICTREX® APTIV® 1000 PEEK Films offers excellent mechanical strength, thermal stability up to 250 °C, and broad chemical resistance, making it ideal for many high-performance applications. Its low outgassing and dielectric properties suit vacuum, microelectronics, and analytical instrumentation. The film’s dimensional stability and low moisture uptake support repeatable results in precision environments. In laboratories, it is widely used in sensors, membranes, and composite structures, enabling researchers to prototype and test in chemically aggressive or thermally demanding conditions. This semi-crystalline film maintains flexibility and formability without compromising integrity across a wide temperature range.
