High NVH Performance. Less Material. Half the Weight
A true advancement in automotive NVH management, the 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.
Each sheet is 21.5" x 16.75", weight is 350 grams
- 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
