Megasorber DIS8

Self-Adhesive Vibration Isolation and Damping Sheet

Features

Vibration Damping and Isolation Sheet

Megasorber DIS8 is a vibration isolation and damping 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.

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 'vibration isolation and constrained layer damping' system. This isolation and damping system provides excellent vibration damping to reduce the low frequency structure-borne noise as well as dramatically increase 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 isolation and damping 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 and buses and trains.

Key Benefits

Australian Made Vibration Dampimg and Isolation Soundproofing Sheet
  • 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 120°C (short term exposure only)
  • 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 120°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

Industrial Manufacturing Noise

Soundproofing Industrial Noise Problem
Hot Steel Balls Created Impact Noise

The impact noise generated from hot steel balls dropping onto a rotating steel wheel was extremely loud—up to 125dB(A). Soundproofing was needed for the 12mm thick steel wheel which had an estimated temperature of about 120°C to 150°C. READ MORE >>

4WD Touring Coach with Noise Problem
High level whining noise caused
discomfort to passengers


4WD coaches used for tourist trips had an extremely annoying whining noise which caused discomfort and headaches for the passengers, especially during long trips. On one occasion, the passengers refused to go back to the bus. READ MORE >>
Soundproofing for
Turret Punch Press Machine

Machine Noise Reduction Semi-Enclosure
A soundproofing semi-enclosure was built around the machine

A turret machine generated an unacceptable noise level that carried into the office environment and made communications in the factory difficult. Megasorber designed a soundproofing semi-enclosure around the machine which reduced the noise to a moderate background sound. READ MORE >>
