Composite vibration damping plate LEGETOLEX D-300

Description
Legetolex is a visco-elastic structural damper offering high damping performance at low weight.

Features

• High performance vibration damping
• Extremely lightweight, reduces overall vehicle weight
• Excellent adhesion to vibrating structures due to a special rubber compound
• Easy to apply on curved or oily surfaces
• Can be applied before or after ED coating
• Design, testing and evaluation in our Automotive Technical Centre (ATC)
• Robotic application possible
• Improves door closing sound

Structure

• Aluminium layer
• Rubber layer
• Release liner

Properties
Initial thickness: 1.5 mm
Constrained layer thickness: 0.127 mm
Adhesion on BA steel: 100 kPa
Mass per unit area: 2300 g/m²

Application
Legetolex is used to damp vibrations of sheet metal panels. It is typically specified for automotive applications but is also used in household appliances (washing machines, dryers, ovens) and other NVH uses. Applying damping material to about 30% of the panel surface generally achieves sufficient noise reduction.
