3M 888519026007 Black Double-sided Foam Tape 45 Mil

Product Description

The 3M 888519026007 is a black double-sided foam tape designed for bonding, mounting, and sealing applications where a conformable, compressible carrier is needed on both bonding surfaces. The tape measures 1/2 inch wide and 5 yards long with a 45 mil total thickness. It uses an acrylic adhesive system, which provides strong initial tack and long-term holding power across a range of substrates including metal, plastic, and painted surfaces. The foam carrier allows the tape to conform to minor surface irregularities, improving contact area and bond strength. This tape is suited for HVAC technicians, electricians, plumbers, and general trade professionals who need a reliable two-sided mounting or gasketing solution in the field or shop.

This double-sided foam tape is commonly used in residential and light commercial trade work for mounting panels, securing insulation, attaching trim or gaskets, and bundling components inside equipment cabinets or enclosures. Its acrylic adhesive performs across a wide operating temperature range, making it suitable for use near HVAC equipment, electrical enclosures, and plumbing chases. The 1/2 inch width is well suited for narrow-channel mounting and tight-clearance installs where wider tape would overlap adjacent surfaces.

Key Features

• 45 mil total thickness for conformability over uneven or textured surfaces
• Acrylic adhesive provides strong tack and durable long-term bond strength
• Tensile strength rated at 90 pounds per inch for secure load-bearing bonds
• Maximum operating temperature of 300 degrees F, suitable for warm equipment environments
• Black foam carrier resists moisture and helps fill minor surface gaps
• 5-yard roll length in compact packaging; one roll per package

Compatibility

Designed as a general-purpose double-sided foam mounting tape suitable for use on metal, plastic, painted, and similar smooth-to-lightly-textured surfaces common in HVAC, electrical, and plumbing trade applications.

Installation Notes

Clean and dry the bonding surface thoroughly before application; oils, dust, or moisture will reduce adhesive contact and bond strength. Firm hand pressure or a roller should be applied along the full tape length after placement to ensure full adhesive contact. This tape is intended for permanent or semi-permanent bonding; removal may damage substrates. Follow applicable trade codes and equipment manufacturer guidelines when using adhesive tape inside electrical enclosures or on heat-generating equipment.
