Self-adhesive composite structure intended to damp vibrations. Materials vibrate and transmit this vibration and/or emit noise. The
T 255 AL 15 damping material absorbs these vibrations. They are dissipated as heat.
The T255 Al tapes are composed of a butyl viscoelastic layer and of a pre-stressed aluminium layer.
The T255 Al tapes are 2 to 4 times lighter than traditional products. They offer better thickness and weight savings while giving identical
performance.
Due to the use of a viscoelastic butyl, the damping performance works over a broad range of temperatures (-30°C to +80°C).
The application is easy even at low temperatures. It matches the contours of the surface when applied.
The visual face is a smooth aluminium foil (pre-stressed layer).
The adhesive face is also protected by a peelable, non-adhering liner.
