Verified laboratory-tested functional tapes engineered for precision electronics masking, aerospace insulation, and mechanical fastening under extreme thermodynamic loads.
Uncompromising surface physics, metallization morphology, and thermodynamic stability designed to conquer tough electrical and thermal barriers.
Silver Mylar Tape utilizes vacuum-metallized biaxially oriented polyethylene terephthalate (BOPET) film. High-purity aluminum is thermally evaporated in a vacuum chamber, creating an ultra-dense reflective layer (mirror silver finish) that blocks radiant heat, UV degradation, and electromagnetic frequencies without adding mass or structural rigidity.
Engineered for electrical winding isolation, our silver polyester films demonstrate exceptional breakdown voltages exceeding 5.0 kV. The underlying crosslinked acrylic or thermosetting rubber adhesive layer retains cohesion under continuous 130°C Class B thermal ratings, preventing dielectric breakdown across transformer cores and power supply modules.
With an optical reflectivity exceeding 92%, silver mylar acts as an exceptional radiative barrier. Its ultra-low longitudinal elongation (<3%) eliminates stretch memory defects during high-speed automated winding, precision slit coil slitting, and computerized die-cut rotary stamping.

Immediate answers for technical directors, sourcing managers, and process engineers qualifying silver mylar solutions.
Aluminum foil tape features a solid metallic foil carrier (25μm–50μm) that is electrically conductive throughout and malleable. Silver Mylar Tape uses a metallized polyester (PET) base film: the thin aluminum vapor deposit provides high reflectivity and chemical protection while maintaining the high dielectric breakdown voltage (>5kV) and high tensile strength of polyester film, preventing electrical short circuits.
Standard Silver Mylar is rated for Class B operations up to 130°C continuous exposure. For high-temperature solder baths (260°C) or powder coating bake cycles (200°C), our Polyimide (Kapton equivalent) or specialized PET High-Temperature Green Silicone tapes are recommended, as standard mylar acrylic adhesives will degrade under extreme temperatures.
We supply two core adhesive options: solvent-resistant crosslinked thermosetting acrylic (offering clean peel, no residue, and excellent aging resistance against oils and solvents) and high-tack synthetic hot-melt/rubber adhesives (delivering aggressive initial tack on corrugated cartons, low-surface-energy plastics, and metal ducts).
Our coating lines apply an ultra-thin topcoat sealant directly over the vacuum-metallized aluminum layer. This microscopic polymer seal shields the metallic deposit from airborne moisture, chemical fumes, and surface friction, preventing yellowing and oxidation even in hot, humid environments.
