Industrial-grade metalized polyester film tape with mirror-like finish, high visibility, and low emissivity. Pressure-sensitive acrylic adhesive, temperature range -60°F to 300°F, ideal for splice detection, reflective applications, and conductive surface requirements.
3M™ Metalized Film Tape 8437 is a premium industrial-grade adhesive tape featuring a metalized polyester backing with mirror-like finish on both sides. This specialized tape combines the advantages of metal tape without the associated weight, making it ideal for applications requiring high visibility and low emissivity. The backing consists of thin, high-tensile strength polyester with metalized coating that provides conductivity while maintaining a bright, reflective appearance for up to 3 months. The tape is mounted on a convenient silicone-coated release liner that facilitates large area applications, die-cutting custom shapes, and precise application control.
The 8437 metalized tape features a pressure-sensitive acrylic adhesive that grabs on contact and holds securely across a wide temperature range from -60°F to 300°F (-50°C to 150°C). With a total thickness of 2.1 mil and width of 2 inches, this tape meets strict low-caliper requirements ensuring it won't interfere with most machinery processes. Each case contains 24 rolls of 72 yards each, providing substantial coverage for industrial and commercial applications. The tape offers exceptional abrasion resistance, protecting surfaces from rough handling and wear, while maintaining its structural integrity and adhesive properties over extended periods.
This metalized film tape is specifically designed for industrial and occupational use, including splice detection, applications where reflectivity and low emissivity are desired, certain applications requiring conductive surfaces, and decorating and identifying applications. The product delivers reliable performance in demanding manufacturing environments, print applications, automotive processes, and specialty vehicle applications where precision, durability, and visibility are critical requirements.
