cost-effective solutions to noise and vibration control
Megasorber DIS8
Self-Adhesive Vibration Damping and Isolation Sheet
Features
Megasorber DIS8 is a vibration damping and isolation material. Using the latest polymer alloy technology, Megasorber DIS8 has a unique polymer blend designed to provide high viscous damping and isolation properties over a wide temperature range with built-in self-adhesive technology (there is no separate glue or adhesive applied to the product).
Megasorber DIS8 is 2mm thick self-adhesive sheet with plastic release liner on both sides. It is designed to be sandwiched between two panels, thus forming a 'constrained-layer damping and isolation' system. This constrained-layer damping system provides excellent vibration damping to reduce the low frequency structure-borne noise as well as dramatically increasing the sound transmission loss.
The built-in self-adhesive technology provides for ease of installation. This unique adhesion enables the product to withstand temperatures up to 180°C without delaminating from the substrate. In addition, Megasorber DIS8 has excellent adhesion to primed steel, lacquered steel, aluminium and low surface energy substrate such as polypropylene and polyethylene.
Megasorber DIS8 complies with IMO Resolution A653(16) for marine applications. Megasorber DIS8 is a light weight vibration damping and isolation material. It is designed to provide maximum vibration damping and isolation without adding much weight. It is one of the most suitable damping material for weight sensitive applications, such as automotive, boats, buses and trains.
Key Benefits
- Reduce panel vibration and resonant noise effectively
- Increase sound transmission loss
- Low installation cost – just peel and stick on
- Suitable for high temperature applications up to 180°C
- Low or non-fire hazard
- Safe and environmentally friendly
Key Features
- High Damping efficiency: Damping Co-efficient (Cd ) when constrained with 1mm thick steel plate or aluminium plate
- The latest built-in adhesive technology – excellent adhesion to most substrates including polypropylene
- Complying with IMO Resolution A653(16) for marine applications
- High temperature resistance – it can stand up to 180°C in overhead and vertical positions
- Low flammability: AS1530.3: 0,0,0,0-1 (with constrained layer)
- Self-adhesive for easy "peel and stick on" application
- Non-toxic
Applications
High efficiency vibration damping and isolation material for reducing impact or vibration induced noise:
- Vibration damping for thick steel substrate: sandwiched between the substrate and 2mm aluminium plate
- Marine industries: sound deadener for aluminium panels when sandwiched between the substrate and 2mm aluminium plate
- Wall partitions: increase the sound transmission loss for plasterboards when sandwiched between the two layers of plasterboard (as shown in images below)
- Floor boards: increase the sound transmission loss and reduce the foot impact noise for floor boards when sandwiched between the two layers floor boards
