Vibration-damping Material LEGETOLEX D-370LE

Legetolex is a visco-elastic, structural damper with a high damping performance and a low weight.

It consists of a thin constraining layer (aluminium or glass cloth) and a self-adhesive synthetic rubber. This combination significantly reduces vibration and noise levels.

Structure

  1. Glass cloth layer
  2. Rubber layer
  3. Release liner

Properties

Initial thickness 1.8 mm
Constraining layer thickness 0.39 mm
Adhesion to BA steel 105 kPa
Weight 2500 g/m²

Application

Legetolex finds its use in vibration damping of sheet metal panels. It is a typical automotive product, although other applications are very common as well (washers, dryers, ovens, etc).
By applying damping material to about 30% of the panel surface, sufficient noise reduction can be obtained.
