High-specification functional tapes engineered for rigorous thermal, dielectric, and mechanical insulation across global manufacturing systems.
Aluminum Mylar Tape (Aluminum Foil-Polyester Composite Film Tape) functions as an indispensable substrate in modern telecommunications, aerospace wiring harnesses, automotive electrification, and high-frequency switched-mode power supplies. By fusing the low electrical surface resistivity of commercial-grade aluminum foil with the high mechanical tensile strength and breakdown voltage of biaxially oriented polyethylene terephthalate (BOPET Mylar), these tapes deliver unmatched dual-functionality: hermetic electromagnetic shielding (EMI/RFI) paired with superior dielectric barriers.

Non-conductive Aluminum Mylar utilizes an insulating pressure-sensitive adhesive (typically acrylic) coated over the PET or aluminum surface, requiring mechanical crimping or drain wires for grounding. Conductive variations incorporate nickel-plated or silver-coated microspheres directly within the adhesive matrix, establishing reliable isotropic Z-axis conductivity through the adhesive layer to ensure grounding upon simple contact pressure.
Copper foil provides higher electrical conductivity and superior EMI attenuation at ultra-low frequencies. However, Aluminum Mylar offers substantial commercial advantages: it is significantly lighter in weight, far more cost-effective, offers greater mechanical elongation without tearing due to the BOPET backing, and prevents galvanic oxidation in corrosive automotive environments.
