3M 9508W Double-Sided Polyethylene Foam Tape, 66 m x 19 mm, White, 0.8 mm Thick, Modified Acrylic Adhesive, 1 Roll KT777306350

When standard mounting tapes fail on uneven or low-surface-energy substrates, the 3M 9508W steps in with a conformable polyethylene foam core and a modified acrylic adhesive that grabs fast and holds long. This white, 66-metre roll is cut to a practical 19 mm width, making it a go-to for everything from interior trim attachment to gap filling and vibration damping. Unlike thin film tapes, the 0.8 mm foam layer absorbs stress, compensates for irregular surfaces, and provides a clean, professional finish without the mess of liquid adhesives.

Highlights

• High initial adhesion for immediate handling strength
• Conformable polyethylene foam backing for uneven surfaces
• Good UV and solvent resistance for indoor and outdoor use
• Long-term temperature resistance up to 70 °C, short-term up to 90 °C
• White PE film liner for easy die-cutting and application

In daily use

The 9508W excels in mounting, bonding, sealing, and gap-filling tasks where a thicker, forgiving tape is required. Its pressure-sensitive modified acrylic adhesive bonds well to many plastics, metals, and painted surfaces, while the foam core dampens vibration and reduces noise. The white liner protects the adhesive until application and releases cleanly, even after storage. Whether you are assembling displays, attaching signage, or securing components in appliances, this tape delivers consistent, reliable performance.
