3M 7010045175 Metalized Polyester Film Tape 8437 Silver

Product Description

The 3M 7010045175 is a metalized polyester film tape sold as 3M Polyester Tape 8437 in silver finish. It features a 1 mil thick metalized polyester film backing combined with an acrylic adhesive system. A silicone-treated paper liner provides easy release during application. The tape is engineered for applications that require high reflectivity and low emissivity performance, making it a practical choice for HVAC, electrical, and industrial trade work where a conductive or reflective surface is needed. Each roll measures 1 inch wide by 72 yards in length.

This tape is suited for splice detection applications, reflective surface requirements, and installations where a conductive tape surface is specified. It performs well in environments where a thin, flexible, metalized film is needed to reflect radiant energy or complete a conductive path. HVAC technicians, electricians, and industrial maintenance professionals commonly use this tape for duct sealing accessories, cable shielding, and reflective insulation facing repairs. The acrylic adhesive provides reliable bonding to smooth and semi-smooth surfaces in typical trade installation conditions.

Key Features

• 1 mil metalized polyester film backing for thin, flexible coverage
• Acrylic adhesive for consistent bond strength on smooth surfaces
• Silicone-treated paper liner for easy, controlled release during application
• High reflectivity and low emissivity properties suitable for radiant barrier and HVAC applications
• Conductive surface supports splice detection and electrical continuity applications
• 1 inch width by 72 yard roll length for standard trade use

Compatibility

Designed as a general-purpose metalized film tape for use in HVAC, electrical, and industrial applications where reflectivity, low emissivity, or a conductive surface is required.

Installation Notes

This tape is applied by hand or with a standard tape dispenser. Ensure the substrate is clean, dry, and free of dust or oils before application to achieve maximum adhesion. When used in electrical or splice detection applications, follow applicable NEC guidelines and de-energize circuits before taping. Avoid stretching the film during application to prevent dimensional distortion of the backing.
