Shop 3M Aluminum Foil Tape 427 Silver 50mm x 55m Industrial Grade In Iraq Best Prices
Premium industrial aluminum foil tape with thermally conductive acrylic adhesive, ideal for heat shielding, thermal management, and chemical masking applications across aerospace, automotive, and electronics industries.
3M™ Aluminum Foil Tape 427 is a premium industrial-grade foil tape engineered for demanding applications across multiple industries including aerospace, automotive, electronics, and construction. This linered version of the 3M™ Aluminum Foil Tape 425 features a dead soft aluminum foil backing combined with a highly engineered acrylic adhesive that provides exceptional heat dissipation and thermal conductivity. The tape measures 50mm in width and 55 meters in length with a 4.6 mil total thickness, delivered in convenient 24-roll cases for bulk industrial applications.
Designed specifically for heat shielding, heat reflection, and thermal management, this tape effectively dissipates heat over its surface to reduce hot spots and protect temperature-sensitive substrates from high-temperature effects. The thermally conductive properties help improve heating and cooling efficiency while the acrylic adhesive maintains a strong, reliable bond even under exposure to high heat and humidity conditions. The tape withstands extreme temperature ranges from -65°F to 300°F (-54°C to 149°C) and resists chemicals, moisture, weathering, and UV exposure, making it ideal for both indoor and outdoor applications.
With its linered backing featuring easy-release film, this tape is perfectly suited for die-cutting applications and provides clean removal after harsh masking operations. Recognized by UL to UL 746C and classified by UL to UL 723 with a Class "L" low flammability rating, the tape meets FAR 25.853(a) specifications and complies with L-T-80C requirements. Whether used for heat shielding delicate parts, chemical paint stripping masking, moisture barriers, light reflection enhancement, or refrigerator and freezer coil attachment, 3M™ Aluminum Foil Tape 427 delivers professional-grade performance and reliability.
