ADHESIVELESS LAMINATE — UNSURPASSED PERFORMANCE
KAPTON® and CIRLEX® polyimide laminates use adhesiveless polyimide bonding technology unique in the marketplace today. Traditional laminates are notoriously unreliable at temperatures which exceed the Glass Transition (Tg) of the adhesives used in their constructions. 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.
CIRLEX® polyimide is the latest addition to our diverse product family. Made from 100% DuPont KAPTON® polyimide laminate film, CIRLEX® is a product that delivers performance and value for some of the most demanding material applications.
SEAMLESS INTEGRATION IN POLYIMIDE
CIRLEX® – an all-polyimide laminate 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.
If you are looking to replace current applications using ceramic or Vespel®, or upgrade
to a new high performance polyimide material, 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 material marketplace.
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.
Broaden your application horizons with 100% polyimide adhesiveless polyimide laminate
Maintains all the excellent performance characteristics – electrical, physical and chemical – of DuPont™ KAPTON®
Available in thicknesses starting at 4 mil (.004”,.20mm)
Improved yields from large and custom sheet sizes
If your application requires high temperature resistance, dimensional stability, low outgassing, durability, and solvent resistance; you need adhesiveless polyimide laminate technology.
