CHEMFILM Engineered for Demanding Applications CHEMFILM® Polyimide Film Polyimide films provide excellent electrical, thermal, physical, and chemical properties over a wide temperature range in a lightweight package (28 m2/kg [136 sq ft/lb] for 1 mil) making them superior for a wide array of applications. CHEMFILM® polyimide films meet exacting tolerances and are produced employing a world-class process that makes them dimensionally stable, inherently isotropic, physically strong, and electrically sound. These products meet all the requirements of ASTM D5213, which superseded MIL-P-46112B. CHEMFILM polyimide films exceed UL 94 V-0 flammability, as well as a 235°C (455°F) Relative Thermal Index (RTI) for both electrical and mechanical properties. Availability CHEMFILM polyimide is available in 0.012, 0.025, 0.05, and 0.076 mm (0.5, 1, 2, and 3 mil) gauges. Rolls are available at a maximum width of 1,570 mm (61.8") with continuous lengths up to 5,000 feet. Advantages • High dielectric strength • Temperature resistance from -265°C to over 400°C (-445°F to over 752°F) • Isotropic • Dimensionally stable • Retains 100% tensile strength (MD) when exposed to MEK, benzene and toulene (ASTM D882) • Scratch and abrasion resistant
