About Formex

ITW Formex manufactures four grades of fire-retardant polymer material — Formex N3, Formex GL, Formex GS and Formex GX. Key features common to all Formex products include:

  • UL 94 V-0 flame class rating, meeting most global safety standards
  • Nonhygroscopic properties, with less than 0.06 percent moisture absorption
  • Excellent chemical resistance and dielectric properties, providing consistent protection against electrical surges

Formex is easy to score and fold, and is sold in convenient sheets that make shipping economical. Different Formex materials offer various temperature resistance and other specialized properties. Formex N3 is a multilayer polycarbonate, whereas Formex GS offers static dissipating ESD protection. All materials meet UL, CSA and IEC safety standards, and are RoHS compliant.


Manufacturers use Formex in applications where superior electrical resistance is required. It is an ideal choice for RFI shielding and insulation in electric vehicles, home appliances, personal computers and medical equipment. Other applications include air baffles and cable management systems in high-end data centers, and barrier protections separating PC boards from housing components.

Formex can be laser cut or die cut using steel rule or rotary dies, allowing for fast prototyping or mass manufacturing with a high degree of accuracy and consistency. Other processing options include heat forming or water-jet cutting. Formex materials can also be embossed, laminated or marked as necessary to support the requirements of a project.
