For decades, 3M has been quietly changing the way OEMs manage noise, vibration and harshness (NVH) in their vehicle designs. Our 3M™ Thinsulate™ Acoustic Insulation is a great example – the first lightweight, low-density cavity-filling product that compresses for efficient installation, and expands to completely fill interior cavities. Today, 3M™ Thinsulate™ Acoustic Insulation is available for a wide range of design and performance criteria. See below to learn more about the 3M™ Thinsulate™ Acoustic Insulation product families, and some additional information on vibration damping tapes.
3M has developed a wide range of Thinsulate solutions to suit your established designs and your most inspired concepts. Each series is available in a wide range of thicknesses, basis weights and surface treatments to help you create unique shapes and profiles that meet specific requirements for your interior application.

Many of our vibration damping tapes feature a pressure sensitive, viscoelastic acrylic polymer adhesive applied to a restraining layer, such as aluminum foil, that combine to achieve effective damping with as little as 20% surface coverage. This construction allows designers a broad ability to control resonant vibrations, and performs across a wide spectrum of temperatures.
Aluminum foil backed anti-vibration tape is designed to reduce structure-borne noise and fatigue in metal and composite panels and support structures. This tape resists moisture, weather, UV degradation and flame, and performs in temperatures from -25°F/32°C to 175°F/180°C). It is easy to die-cut and to apply, and meets the requirements of F.A.R. 25.853(a) and can pass ASTM E-162 and ASTM-E 662 for flammability and smoke generation.
