3M™ Engineered Damping Material EDM1029, 2.9 mm, Aluminum

Description

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
