Sn-Cu-PET Foil for Electromagnetic Shielding


Sn-Cu-PET is a composite material combining rolled copper foil and PET film. It is lightweight and has excellent shielding properties at high frequencies and good heat and corrosion resistance due to tin plating on the copper foil surface.

Hot-melt Adhesive Type

Double-sided Tape Type*contact us for thickness change

  • Sn-Cu-PET (hot-melt adhesive type) has been adopted for cables on vehicles.
  • JX has started providing samples of Sn-Cu-PET (double-sided tape type).

Shielding Effectiveness

Sn-Cu-PET foil has excellent EMI shielding effect in wide range frequencies.
