Part Number: 431 Width: 25.4mm Length: 54.9m Thickness: 0.19mm Manufacturer: 3M Thermal conductive tape dissipates heat, improving heating and cooling efficiency and protecting temperature-sensitive materials. The highly engineered acrylic adhesive provides long-term durability and removes cleanly even after demanding masking applications. The extremely soft aluminum foil backing conforms to curved and irregular surfaces. Resists flame, weathering, moisture, and UV exposure. The heat and light-reflecting tape protects surfaces and enhances lighting efficiency. A high-performance foil tape designed for a variety of applications across a wide range of industries. It consists of an extremely soft aluminum foil backing and a highly engineered pressure-sensitive acrylic adhesive, making it ideal for heat shielding, heat reflection, light enhancement, seaming, and sealing. Durable and resistant to high heat and humidity. Aluminum Foil Tape 431, made with an extremely soft, thermally conductive aluminum backing, disperses heat across the tape's surface to reduce hot spots and protect substrates from the effects of high temperatures. Coated with a highly engineered acrylic adhesive, it can withstand exposure to high heat and humidity while maintaining a strong and reliable bond. This tape can withstand a variety of moisture, weathering, UV, and solvents to provide excellent working life, both indoors and outdoors. Complies with FAR 25.853(a). Operating temperature range is -65° to 300° F (-54° to 149° C). Recommended Applications Thermal shielding for delicate components Heat reflection Moisture barrier Light enhancement through light reflection Seaming and sealing Refrigerator and freezer coil attachment Protection of plastics against heat and UV This product was originally sold at a high price, so discounts are not available.
