3M™ Sound Damping Aluminum Foam Sheets

3M™ Damping Aluminum Foam Sheets, open cell polyurethane foam with aluminum constraining layer on one side and a pressure sensitive acrylic adhesive on the opposite side, easy release liner. Designed for damping resonant vibrations in thin sheet metal, resulting in attenuated resonant amplitudes and consequent noise reduction.

Benefits:

• Excellent damping per pound of material used and installed cost ratio
• Easy to apply - only hand pressure required
• Good thermal insulator and heat reflector
• Excellent moisture resistance, aging properties and fatigue resistance
• Meets Federal Air Regulation Flammability Specifications for acoustical insulation materials (F.A.R. Section 25.853, Paragraph B)
