Cirlex® - Laminated Kapton® Film
Cirlex® Laminated Kapton® Film is an all-polyimide sheet material — has been developed to fill the growing requirement for thick all-polyimide materials, stemming from a wide variety of industries such as automotive, aerospace, and electronics. Cirlex® offers material flexibility and an expanded range of thickness options unattainable with cast resins or laminated constructions using adhesives. Offering the excellent chemical, physical, thermal and electrical properties of Kapton® in thick sheet format is unique in today's marketplace. Traditional laminates are notoriously unreliable at temperatures which exceed the Glass Transition (Tg) of the adhesives used in their constructions. You can count on Cirlex®'s integrity at extreme temperatures, from cryogenic [-269°C (-452°F)] to as high as 351°C (664°F); and it is readily modified/machined by laser cutting, drilling, machining and chemical etching. Kapton® and Cirlex® laminates use adhesiveless bonding technology unique in the marketplace today. Eliminate the adhesive and you eliminate the weak link in the chain. Use of all polyimide bonding eliminates the adhesive interface where many problems occur. Polyimide is closely matched to the CTE of copper, and can also be used to bond many other metals with bond strengths typically > 10 pli.
