Dual Conductor Copper Foil Tape for EMI Shielding and Electrical Conduction

The Dual Conductive Copper Tape consists of two layers of thin copper foil bonded to a polymer carrier film. It provides effective electromagnetic interference (EMI) shielding and grounding due to the high conductivity of copper. The dual conductive layers allow twice the current capacity compared to single-layer copper foil. The tape offers reliable adhesion and conforms well to complex surfaces and irregular shapes. It is often used for EMI shielding and grounding in electronics, electrical appliances, automotive, aircraft and telecom applications. This dual conductor copper foil tape delivers twice the power in a compact form for efficient EMI shielding and electrical conduction.

Due to its excellent EMI shielding characteristics, heat resistance, and chemical resistance, the conductive copper foil tape is widely used in the electronics industry for products such as transformers, mobile phones, computers, PDAs, PDPs, LCD displays, laptops, and photocopiers that are susceptible to electromagnetic interference (EMI). It is also used for wrapping steam pipes to prevent heat loss. It can replace magnet wires and various types of transformer shielding.
