ITW Formex® flame retardant materials provide superior electrical insulation and barrier materials in industrial and consumer electronic equipment. The electrical insulating material is available in rolls, sheets, and panels and can be easily fabricated into a wide range of shapes.

Easily Fabricated

No other flame retardant, electrical insulating materials can match the flexibility and performance of Formex™ for cost-effective fabricated parts. Formex™ has successfully replaced a variety of electrical papers, thermoplastic materials, and injected molded parts.

Parts fabricated from Formex™ are cost-effective replacements for injection molded or sheet metal parts used inside electrical equipment. In these applications, Formex™ parts not only are easier to use, they also reduce tooling and fabricating expenses and cut inventory and warehousing costs. See how Formex compares to fish paper and aramid paper.

DuPontTM 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 DuPontTM KAPTON® in thick sheet format is unique in today’s material 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 220°C (428°F); and it is readily modified/machined by laser cutting, drilling, machining and chemical etching.

Incomparable Performance in Adhesiveless Technology Laminates

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.  If your application requires high temperature resistance, dimensional stability, low outgassing, durability, and solvent resistance; you need CIRLEX® adhesiveless laminates.
