3M™ Engineered Damping Material EDM1029 delivers high NVH performance from smaller parts at lower weight than traditional CLDs. It damps structure-borne noise in designs using lightweight substrates without adding significant weight. Flexible, conformable, adhesive-backed and customizable, this thin 2.9 mm material installs more easily, more cleanly and in more places vs. Al butyl or bitumen.
3M Engineered Damping Material features an engineered stem web layer between two layers of adhesive
High NVH Performance. Less Material. Half the Weight
A true advancement in automotive NVH management, our 3M™ Engineered Damping Material EDM1029
(PDF, 240.85 Kb) allows you to use smaller, lighter-weight parts for equal performance vs. conventional CLD solutions. This 2.9 mm-thick material features an engineered stem web layer between two layers of adhesive. Along with an aluminum constraining layer, this construction delivers the damping performance of a conventional CLD like Al butyl or bitumen, at half the weight. It is excellent for damping structure-borne noise, which is critical as OEMs continually incorporate lighter-weight substrates such as thin-gauge steel, aluminum and composites into their vehicle designs. It is a great alternative to traditional damping as OEMs strive to meet fuel efficiency and CO2 regulations. It meets the requirements of many OEMs for low interior VOCs.

Easy, Clean Installation Nearly Anywhere on the Vehicle
3M™ Engineered Damping Material is a flexible, conformable material that can be applied uniformly even to complex shapes. Its adhesive backing allows for easy, precise and permanent installation — even to inverted or vertical areas where other CLDs have been difficult to install, such as roofs and door panels. It also adds stiffness to the substrate, along with better surface contact for better damping performance.
The flexible material applies easily to irregular or curved surfaces
Why Automotive Manufacturers Choose 3M Engineered Damping Material:
- Rear wheel arches
- Spare tire areas
- Customizable for nearly any area of the vehicle
About 3M and the Science of Sound
