Medical High Performance

Medical High Performance Materials

Medical high performance materials are needed for a variety of applications including adhesion bonding, insulation, membranes, vibration dampening, chemical resistance, and thermal management. Fralock’s high performance materials possesses a unique combination of properties that enable this material to maintain its excellent physical, electrical, and mechanical properties over a wide temperature range making it appealing to a wide range of industry applications. It can be easily laminated and con­verted to a custom size and shape.

Fralock’s medical high performance material combines heat resistance, dimensional stability, and chemical resistance, to be used in hostile and extreme environmental conditions. Unlike most plastics, it does not produce significant outgassing even at high temperatures. It also performs well in vacuum applications, down to extremely low cryogenic temperatures.

Whether your application requires survivability beneath the earth’s surface, above earth’s atmosphere or somewhere in between, Fralock has been involved in a variety of composite material projects that required custom conversion of specialty materials.

Fralock is ISO and AS Registered, and we are ITAR registered.


Traditional laminates are notoriously unreliable at temperatures which exceed the Glass Transition (Tg) of the adhesives used in their constructions.

Fralock’s medical high performance DuPontTM KAPTON® and DuPontTM CIRLEX® polyimide laminate use adhesiveless polyimide 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.
If your application requires high temperature resistance, dimensional stability, low outgassing, durability, and solvent resistance; you need adhesiveless polyimide laminate technology.


CIRLEX® Manufactured by FRALOCK®

For over 50 years Fralock has supplied high-quality materials for the global marketplace.   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.


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®.
