3M 7000123930 Vhb Foam Tape 1 Inch X 36 Yard 25 Mil Gray

Product Description

The 3M 7000123930 is a gray, double-sided, pressure-sensitive, closed-cell acrylic foam tape sold in a 1-inch-wide by 36-yard roll at 25 mil thickness. It features a PE film liner for handling convenience and is designed for bonding high and medium surface energy substrates. The acrylic foam core provides cushioning, vibration damping, and impact resistance. Its closed-cell construction makes it resistant to plasticizer migration, which helps maintain bond integrity over time in demanding environments. Installation does not require liquid adhesives or mechanical fasteners, reducing assembly steps for fabricators, installers, and maintenance technicians working in HVAC, electrical, and general trade applications.

This tape is suited for applications where a firm, conformable bond is needed between substrates such as metal, glass, and high-surface-energy plastics. Common use cases include panel attachment, gasket-style sealing, equipment mounting, and vibration isolation in both residential and light commercial settings. The 36-yard roll length is practical for repetitive bonding tasks on the job site or in a shop environment. Its gray color allows it to blend with metal surfaces in visible installations.

Key Features

• 25 mil total thickness for gap-filling and conformability on slightly uneven surfaces
• Closed-cell acrylic foam construction resists plasticizer migration
• Bonds high and medium surface energy substrates without liquid adhesives
• Provides cushioning, vibration damping, and impact resistance in bonded assemblies
• PE film liner for clean handling and precise application
• UL listing 746C for use with polymeric materials

Compatibility

Designed for bonding high and medium surface energy substrates including metals, glass, and select plastics. Suitable for fabrication, panel mounting, and equipment assembly tasks across HVAC, electrical, and general trade industries.

Installation Notes

Surface preparation is critical before applying pressure-sensitive foam tape — clean and dry substrates free of oils, dust, and loose material will produce the strongest bond. Apply firm, even pressure across the full tape surface after positioning to achieve full adhesive contact. Minimum application temperature requirements should be observed; consult the product data sheet for temperature range details. This tape is intended for permanent or semi-permanent bonding and should not be used as a substitute for structural fasteners in load-bearing applications.
