Composite vibration damping plate LEGETOLEX D-350

Overview
Legetolex is a visco‑elastic structural damper composed of a glass cloth layer, a rubber damping layer and a release liner. It is designed for vibration damping of sheet‑metal assemblies in automotive and industrial applications.

Features

• High damping performance with a constrained rubber layer
• Low areal weight for minimal impact on overall structure mass
• Good adhesion to vibrating substrates due to a specially formulated rubber compound
• Suitable for application on curved or slightly oily surfaces
• Can be applied before or after ED (electrodeposition) painting
• Validated by design and testing in the Automotive Technical Centre (ATC)
• Compatible with robotic application
• Contributes to improved door closure acoustics

Structure

• Glass cloth layer
• Rubber (visco‑elastic) layer
• Release liner

Properties
Initial thickness: 2.2 mm
Constraining layer thickness: 0.2 mm
Adhesion to BA steel: 140 kPa
Weight: 3200 g/m²

Application
Legetolex is applied to sheet metal panels to reduce vibration and radiated noise. Typical uses include automotive body panels and a variety of industrial appliances (washers, dryers, ovens). Applying damping material to approximately 30% of a panel surface typically yields effective noise reduction.
