3M 7010045176 Metalized Polyester Film Tape 8437 Silver

Product Description

The 3M 7010045176 is a metalized polyester film tape sold as Tape 8437 in silver finish. It features a 1 mil polyester film backing with a metallic coating and an acrylic adhesive bonded to an easy-release silicone-treated paper liner. The tape measures 0.5 inches wide by 72 yards per roll. It is designed for applications where surface reflectivity and low emissivity performance are required. HVAC technicians, sheet metal workers, and industrial maintenance professionals commonly use this tape in insulation, ductwork, and equipment fabrication environments.

This tape is suited for both commercial and industrial applications where a conductive or reflective surface is needed. It performs well in splice detection applications, allowing technicians to identify joint locations using detection equipment. The low-emissivity metalized surface also makes it a practical choice for thermal management and radiant barrier work. Its acrylic adhesive provides stable bonding across a range of surface types encountered in trade work.

Key Features

• 1 mil metalized polyester film backing for durability and flexibility
• Acrylic adhesive with easy-release silicone-treated paper liner for clean application
• High reflectivity and low emissivity surface for thermal and radiant applications
• Suitable for splice detection where conductive surface marking is required
• 0.5 inch width in a 72-yard roll for extended coverage per unit

Compatibility

Designed for use in applications requiring a reflective, low-emissivity, or conductive tape surface, including HVAC ductwork, insulation splicing, and industrial equipment fabrication.

Installation Notes

This tape is applied by hand and requires no special tools beyond a tape dispenser or cutting implement. Surfaces should be clean, dry, and free of dust or oil before application to ensure proper adhesive bond. No power shutoff is required for tape installation, though standard job-site safety practices apply. Follow applicable building and mechanical codes when using tape in duct or insulation assemblies.
