Self-adhesive Constrained-layer Vibration Damping Sheet

Features

Megasorber D14 is a unique constrained layer vibration damping material, as it provides consistent damping performance over a wide temperature range. Using the latest polymer alloy technology, Megasorber D14 is a blend designed to provide high viscous damping properties combined with built-in self-adhesive technology (there is no separate glue or adhesive applied to the product).

This built-in self-adhesive technology enables the product to withstand temperatures up to 180°C. In addition, Megasorber D14 has excellent adhesion to primed steel, lacquered steel, aluminium and low surface energy substrate such as polypropylene and polyethylene.

Megasorber D14 complies with IMO Resolution A653(16) for marine applications.

Megasorber D14 is a light weight vibration damping material. It is designed to provide maximum damping without adding much weight. It is one of the most suitable damping material for weight sensitive applications, such as automotive, boats and buses and trains.

The aluminium foil provides excellent heat reflection. Megasorber D14 is widely used as a self-adhesive vibration damping material, an acoustic sealer to seal holes and openings as well as heat shield patches.

Key Benefits

• Reduces panel vibration and resonant noise effectively
• Ease to apply—just peel and stick
• Suitable for high temperature applications up to 180°C
• Low or non-fire hazard
• Excellent heat reflector and thermal insulator
• Safe and environmentally friendly

Applications

High efficiency vibration damping material for reducing impact or vibration induced noise. Typical applications include:

• Metal roof panel damper—reduce rain drop impact noise
• Reduce impact and vibration induced noise of metal panels in enclosures and metal housing
• Marine industries—sound deadener for aluminium panels
• Disk drives damper
• Medical equipment
• Vehicle metal panel damper
• Trim panel damping in locomotives, trains, trucks
• Heat shield patches near exhaust or heat source in motor vehicles
