Copperfoils and -tapes

Cable Industry: Copper foils and laminates (e.g. CU/PET, CU/PP) are widely used for shielding and grounding in high-frequency, data, and specialty cables. They enhance EMI shielding, reduce signal loss, and offer mechanical protection.

Shielding and Electromagnetic Protection: Copper tapes are applied (either longitudinally or helically) around conductors or insulation layers to shield the cable from electromagnetic interference (EMI) and ensure a consistent electrical potential.

Conductive Shield in Medium- and High-Voltage Cables: In cables with solid or foamed insulation, copper tapes act as conductive shields that safely control and discharge electric fields and voltages, increasing operational reliability.

Grounding and Short-Circuit Current Carrying: Copper tapes provide a safe grounding path and serve as a current-carrying layer to conduct short-circuit currents, helping protect equipment and personnel in fault conditions.

Mechanical Protection and Structural Integrity: In addition to their electrical role, copper tapes add mechanical strength to the cable and protect inner layers from damage due to bending, pressure, or external forces.

Electronics and Printed Circuit Boards (PCB): Pure copper foils and composite structures like CU/PI/CU or CU/PET/CU are key materials in both rigid and flexible PCBs. They allow for precise circuit patterns and ensure reliable signal transmission in electronic devices.

Flexible Electronics: Laminates with polyimide (CU/PI) or polyester (CU/PET) are used in flexible circuits and wearable electronics, combining electrical performance with mechanical flexibility and thermal resistance.

Adhesive Tape Manufacturing: Copper foils are used as carrier materials in electrically conductive adhesive tapes, ideal for EMI shielding, ESD protection, grounding, and electrical connections.
