Copper sheathing slitting tapes thermal conductive for EMI shielding

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.
