3M™ Damping Aluminum Foam Sheets 4014

• Sheets make for excellent per-pound installed cost ratios on larger jobs such as sound-absorbing wall panels
• Absorbs and dissipates vibration and reduces noise in metal and plastic panels
• Durable aluminum backing resists aging and moisture
• 250 mil (6.35 mm) open-cell, polyurethane foam absorbs and attenuates vibration
• Acrylic adhesive aggressively bonds to structural surfaces
• Easy to apply – only hand pressure required
• Meets Federal Air Regulation Flammability Specifications for acoustical insulation materials (FAR Section 25.853, Paragraph B).

3M™ Damping Aluminum Foam Sheets 4014 are a vibration and noise reduction material provided in sheets for excellent per-pound cost ratios. Open cell polyurethane foam with an aluminum-urethane constraining layer absorbs panel vibration and dissipates it to negligible heat, reducing resonant noise and fatigue. Pressure-sensitive adhesive and easy-release liner make for fast, smooth application of this soundproofing material.

Sized for applications with larger damping areas such as sound absorbing wall panels, 3M™ Damping Aluminum Foam Sheet 4014 attenuates and reduces the resonant sound and vibration in thin sheet metal, plastic panels and support structures. It features a 250 mil (6.35 mm) open cell polyurethane foam with a 3.0 mil (0.01 mm) aluminum-urethane backing. It applies quickly and easily to the vibrating component by a strong, pressure-sensitive acrylic adhesive and only finger pressure is required to establish a lasting bond.

Suggested Applications

• May be used in vibration and shock isolation designs
• Ideal for sealing, seaming, joining panels, and vibration damping
• Intended for general industry use, as well as automotive, aerospace, electrical, and mechanical industries
• Great for sound absorbing wall panels
