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
