3M 7000028881 Vinyl Foam Tape Black 0.5 in X 36 Yd

Product Description

The 3M 7000028881 is a single-coated, closed-cell vinyl foam tape designed for bonding and sealing applications across a wide range of surfaces. Marketed as 3M Vinyl Foam Tape 4718, this roll measures 0.5 inches wide by 36 yards long and is 0.125 inches thick. The conformable vinyl foam construction allows the tape to follow irregular contours and compressed gaps, creating a reliable seal even on uneven substrates. The black finish and closed-cell foam structure help resist moisture intrusion and compression set over time. HVAC technicians, electricians, and general trade professionals use this tape where a compressible, adhesive-backed sealing material is required.

This tape is suited for residential and commercial applications where flexible sealing, vibration dampening, or surface bonding is needed. Common use cases include sealing gaps around ductwork, electrical enclosures, panels, and other assemblies where a conformable foam barrier improves insulation or prevents air and moisture infiltration. The single-coated construction means one side carries the adhesive while the foam backing provides cushion and fill for irregular mating surfaces.

Key Features

• Closed-cell vinyl foam construction resists moisture and compression set
• Highly conformable for bonding to irregular or textured surfaces
• 0.125 inch thickness provides gap-filling and cushioning in tight assemblies
• Single-coated adhesive on one face for direct surface bonding
• Black color suitable for applications where tape visibility should be minimized
• 36-yard roll length reduces changeover frequency on repetitive sealing tasks

Compatibility

Designed for bonding and sealing to a variety of surfaces as an OEM-style closed-cell foam tape solution for HVAC, electrical, and general trade sealing applications.

Installation Notes

Surface preparation is critical before applying foam tape — clean the mating surface of oil, dust, and loose material for maximum adhesion. Apply firm, even pressure across the full tape width after placement to ensure full contact between the adhesive and the substrate. No special tools are required beyond a cutting implement and a roller or hand pressure device. Follow all applicable building and mechanical codes when using tape as part of an air sealing or insulation assembly.
