Discover sound solutions in automotive NVH

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.

• Quieter Vehicles. Provides highly efficient acoustic absorption, particularly in middle- to high-frequency ranges.
• Lighter Vehicles. Thinsulate acoustic insulation products are made from lightweight polyester and polypropylene non-woven fibers.
• Easy to Install. Lightweight and easy to handle compared to fiberglass, shoddy, felt and PET.
• Mold, Mildew and Moisture Resistant. Install just the insulation — there's no need for an additional waterproof layer during application. Thinsulate acoustic insulation is also resistant to mildew growth, reducing the risk of offensive odors.
• Efficient Assembly. Attach our acoustic insulation using a variety of methods including ultrasonic welding, double-sided tape or mechanical clips.
• Manufacturing Support. Thinsulate acoustic insulation is supported by a global network of 3M experts. Custom die cutting services are available.

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.
