Lightweight, Low Cost Aluminum Foil/Polyester Film for EMI Shielding

Z-Foil® is comprised of an Aluminum foil material with a laminated film of Mylar (Polyester) on one side and a pressure sensitive adhesive closure.

You’ll find Z-Foil® very useful in high-frequency EMI/RFI shielding applications where an economical, lightweight, low-profile shielding is wanted and re-entry is not needed. The SH1 Aluminum foil material is excellent as a general-purpose shielding product in areas such as an electronics rack. This product should not be used where a great deal of flexing may occur.

Z-Foil® is great for both round and flat cable shielding requirements and is available with or without a tin/copper ground wire. This product is flame retardant, and has an operational temperature range of -45° to 150°C (-49° to 302°F).
