Superior Heat Dissipation and Thermal Conductivity: The 3M™ Aluminum Foil Tape 431 effectively dissipates heat across its surface, reducing hot spots and protecting temperature-sensitive materials. This makes it ideal for use in environments where maintaining optimal thermal conditions is critical.

Highly Durable Acrylic Adhesive: The tape is coated with a highly engineered acrylic adhesive that provides long-lasting durability, even under harsh conditions. It maintains a secure bond in high heat, humidity, and exposure to moisture, UV light, and solvents, yet removes cleanly when needed, making it suitable for both temporary and permanent applications.

Flexible and Conformable Design: The dead soft aluminum foil backing easily conforms to curved and uneven surfaces, ensuring reliable performance even in complex and challenging applications. This flexibility allows for seamless application on a variety of surfaces.

Protection Against Environmental Elements: Designed to withstand exposure to flame, weathering, moisture, and UV light, this tape offers robust protection for your materials, whether used indoors or outdoors.

Low Flammability Rating: Classified by UL to UL 723, Class “L,” the 3M™ Aluminum Foil Tape 431 has a low flammability rating, providing peace of mind when used in environments with strict safety standards.

Reflective Properties for Light and Heat Management: Its heat and light reflective properties help protect surfaces from heat damage while enhancing lighting efficiency in various applications.
