3M 7000144639 Foam Tape 4004 Off-white 1in X 18yd 0.25in Thick

Product Description

The 3M 7000144639 is a double coated, open-cell urethane foam tape sold under the 3M 4004 series. At 0.25 inches thick, the tape carries adhesive on both faces and includes a paper release liner for clean, controlled application. The open-cell foam core bonds to irregular and uneven surfaces while simultaneously filling gaps and providing cushioning. The off-white color aids visual confirmation of placement during assembly. This tape is typically handled by maintenance technicians, HVAC installers, and industrial assembly professionals who need a conformable bonding medium that can absorb minor surface variation.

This tape is suited for bonding, gap-filling, and cushioning applications in both light commercial and industrial settings. The 1-inch wide by 18-yard roll format is practical for smaller paneling, gasket work, vibration dampening, and weather sealing tasks where a thick, conformable foam layer is required. Open-cell construction allows slight compression under clamping or fastening force, helping maintain consistent contact across uneven substrates.

Key Features

• Double coated construction — adhesive on both faces for immediate bonding to two surfaces simultaneously
• 0.25-inch thick open-cell urethane foam core conforms to irregular and uneven surfaces
• Paper release liner provides handling convenience and protects adhesive until application
• Gap-filling capability reduces need for surface prep on slightly rough or mismatched substrates
• Cushioning properties help absorb vibration and mechanical shock in assembled joints
• Off-white color aids visual placement confirmation during installation

Compatibility

Designed as a general-purpose double coated foam tape suitable for bonding, sealing, and cushioning on porous and non-porous surfaces in light commercial, HVAC, and industrial assembly applications.

Installation Notes

Surface should be clean, dry, and free of oil or dust before applying tape for maximum adhesion. Peel the paper liner just before pressing the tape firmly into place to avoid adhesive contamination. When trimming to length, use a sharp utility knife or shears to maintain a clean edge. Handle with care to avoid stretching the foam core before bonding, which may reduce effective thickness and gap-fill performance.
