With Black Glue Single Sticky Adhesive Copper Foil Tape for EMI Masking, 4mm, 5mm, 6mm~20mm width

Featuring a 99.95% high-purity copper foil backing and specialized black acrylic adhesive, this single-sided conductive copper foil tape provides superior electromagnetic interference (EMI/RFI) shielding, reliable grounding, and anti-reflective light masking. The black adhesive layer blends discreetly into dark electronics housings, preventing visible reflections and light bleeding while maintaining low surface electrical resistance (0.03Ω–0.05Ω) and heat resistance up to 120°C.

Key Features

• Anti-Reflection & Light Masking: The specialized black adhesive absorbs light and prevents optical glare or shine-through in narrow display bezels, cameras, and optics.
• High-Performance EMI/RFI Shielding: Effectively blocks high-frequency electromagnetic radiation and eliminates signal cross-talk in sensitive electronics.
• Thermal Dissipation: High thermal conductivity of copper assists in dissipating heat from hot spots on microprocessors, LED arrays, and circuit boards.
• Conformable & Easy to Apply: Thin 0.06mm profile flexes easily around contours, corners, and tight internal device enclosures.

Recommended Applications

• Consumer Electronics: EMI shielding and static grounding in smartphones, laptops, tablets, PDP/LCD displays, and printers.
• Power & Transformers: Coil wrapping, transformer core shielding, and motor interference suppression.
• Thermal Management: Heat spreading and thermal transfer for LED modules and compact internal components.
• Optics & Sensors: Light-absorbing shielding for cameras, light sensors, and optical instrumentation.

Storage & Handling Tips: Store in a cool, dry, and well-ventilated area away from direct sunlight and moisture to maintain optimal adhesive performance.
