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 16.92"
- 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
