Key Features
EMI/RFI Shielding Performance
Copper foil provides effective shielding for electromagnetic and radio-frequency interference. It is suitable for electronics, cables, control cabinets, laptops, sensors and other sensitive components.
Excellent Electrical Conductivity
The copper foil surface offers reliable conductivity for grounding, electrical connection, conductive paths and repair applications.
Conductive Adhesive Available
For applications that require conductivity through the adhesive layer, conductive adhesive options are available. Non-conductive adhesive can also be supplied for general bonding and shielding use.
Heat Resistant Protection
Copper foil has good thermal conductivity and can be used for heat spreading, heat-resistant protection and electronic maintenance applications. Heat resistance depends on the adhesive type, and high-temperature adhesive can be customized.
Solderable Copper Surface
The copper surface can be soldered, making it suitable for circuit repair, grounding points, electrical modification and DIY electronics projects.
Flexible and Easy to Apply
The tape can be cut, folded, wrapped and shaped to fit flat, curved or irregular surfaces.
Custom Width Available
Narrow widths are suitable for fine electrical repair and precision shielding, while wider rolls can be used for large-area shielding and industrial applications.

Usage Instructions
Clean the surface before application.
Make sure the surface is dry and free from dust, oil or oxidation.
Cut the copper foil tape to the required length.
Peel off the release liner carefully.
Apply the tape to the target surface and press firmly.
For grounding or conductive connection, make sure the copper surface contacts the required conductive area.
For soldering, apply heat carefully and test before mass use.
Important Notes
For applications requiring conductivity through the adhesive layer, please choose the conductive adhesive version. Standard adhesive copper foil tape may only provide conductivity on the copper foil surface. Heat resistance depends on adhesive type, application temperature and bonding surface. Testing is recommended before mass production or critical electrical applications.
