Single-Sided Conductive Copper Foil Tape for EMI Shielding & Electronics

Ensure reliable electromagnetic interference (EMI) protection and electrical conductivity with this Single-Sided Conductive Copper Foil Tape. Crafted from 99.98% pure copper foil with a silver-plated treatment on one side and backed by a conductive acrylic adhesive, this high-performance tape delivers superior signal shielding (>85 dB) and low electrical resistance (≤0.05 Ω) across sensitive electronic circuits and audio equipment.

Key Features

• High-Efficiency EMI & RFI Shielding: Provides greater than 85 dB attenuation against electromagnetic and radio frequency interference to eliminate humming, buzzing, and signal loss.
• Conductive Acrylic Adhesive: Delivers strong peel adhesion (≥1500 g/25mm) with stable electrical conductivity through the adhesive layer.
• Single-Sided Silver Finish: Features high-purity copper foil paired with a specialized silver-colored backing for enhanced surface protection and grounding performance.
• Flexible & Malleable: At approximately 0.05mm total thickness, the tape easily conforms to tight curves, irregular contours, and compact enclosures.
• Thermal Stability: Operating temperature range from -10°C to 120°C (14°F to 248°F) for dependable performance in demanding industrial and electronic environments.

Application & Storage Guidelines

• Surface Preparation: Clean and dry the bonding surface thoroughly (using isopropyl alcohol if needed) to remove oil, dust, and moisture before application.
• Application: Apply firm, uniform pressure along the length of the tape to activate the pressure-sensitive adhesive and maximize conductivity.
• Storage: Store rolls in a dry, well-ventilated space away from direct sunlight and extreme humidity.
