3M™ Engineered Damping Material EDM1029
- 3M Product Number EDM1029
- 3M ID B5005093054
Details
Highlights
- Delivers comparable or better performance to conventional constrained layer damping (CLD) materials and is less than half the weight
- Stand-off layer features low-density engineered stem web that optimizes damping performance
- Damps structure-borne noise when lighter materials such as thin-gauge steel, aluminum and composites are used, without adding significant weight
- Flexible, conformable material applies uniformly to complex shapes
- Adhesive backing improves wet out and won't delaminate even at high temperatures
- Can be installed in vertical or inverted applications
- Meets requirements of many OEMs for low interior VOCs
- Thickness of 2.9 mm allows for a wide range of installations where space is limited
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
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.

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
- Roofs
- Doors
- Trunks
- Floors
- Rear wheel arches
- Spare tire areas
- Customizable for nearly any area of the vehicle
Why Automotive Manufacturers Choose 3M Engineered Damping Material:
- High damping performance. Constrained-layer material provides excellent acoustic damping across a range of frequencies, with advantages over traditional materials at temperatures above 40°C.
- Lighter weight. Engineered web stem construction delivers similar performance in much smaller parts vs. Al butyl or bitumen.
- Easy to use. Integrates quickly into OEM general assembly processes.
- Easy to install. Conformable material handles well and applies uniformly across irregular or complex surfaces.
- Can be used in more places. Adhesive backing makes for precise, permanent application, well-suited for roofs and door panels. It can be customized for nearly any area of the vehicle.
- Manufacturing Support. 3M Engineered Damping Material is supported by a global network of 3M experts. Available in a variety of standard sizes, with custom die cutting services available as required.
