CIRLEX® DATA SHEET
CIRLEX® 100% polyimide film has been used successfully in an array of applications due to its stability from temperatures as low as -269°C (-452°F) and as high as 400°C (752°F). CIRLEX® has excellent wear and friction properties,very good electrical and physical properties, and is impervious to most chemicals. Fralock manufactures CIRLEX® to rigorous standards using 100% KAPTON® polyimide composite materials to achieve these high performance characteristics. The glass transition temperature of 351°C provides for exceptional stability and reliability across a broad temperature spectrum.
CIRLEX® benefits designers and users in aerospace, electronics, electrical, semiconductor, and chemical industries, among others, because of its excellent mechanical and electrical properties, dimensional stability, ease of machining, low out gassing characteristics, creep resistance, wear resistance and chemical inertness.
- CIRLEX® is available in stock sheet sizes of 13.5” x 23.5” or 23.5” x 23.5”
