Ideal for EMI shielding, thermal and electrical conductivity  

Polyester PET film backed Copper foil (Cu) is a highly conductive, EMI shielding material, comprised of a bright finished copper foil laminate with a clear polyester PET film. This material offers a 28lb. breakage strength per inch-width.

The copper laminate foil is typically used as a salt corrosion resistant shield in military applications, however this material has also been used in aerospace and many other industries. The foil could be used as a wrap-around tape, or be used in conjunction with other materials to engineer a solution that will meet your particular EMI shielding needs.


  • Salt corrosion resistant EMI shield for hardening electrical cables.


  • Operating temperature range of -22°F to 248°F
  • Perfect for a wide variety of military and aerospace applications.
