Megasorber DT2S Self-Adhesive Vibration Damping Tiles
used in Melbourne's Latest Trams
Soundproofing Project Summary
1. Pin-point the vibration "hot-spots"
The engineering team "mapped" out the target damping treatment areas:
2. Customise the damping tile DT2S
Two sizes were designed to optimize the damping performance:
3. Validation of the damping performance
The performance of the damping tiles was tested and the damping decay rate was found to be 80.2 dB / second, well exceeding the target of 75dB
/ second. The test results are shown below:
4. Heat resistance test: heat soak cycles
The durability of the damping tiles was tested at four temperatures:
24 hours oven test at 90°C
24 hours oven test at 130°C
24 hours oven test at 150°C
24 hours oven test at 180°C
Samples were not cooled in-between individual stages of the heat soak test, i.e. after 24 hours exposure to 90°C the temperature was raised to
130°C and the test was continued. It took oven about 30 minutes to get to the new temperature level.
After the test the samples had no delamination:
5. Easy installation
It is a just “peel and stick on” application:

We can tailor the Megasorber light-weight soundproofing solution to meet with your requirements.
The automotive industry demands top performing products at minimal cost. At Megasorber, we have taken up this challenge. By combining our expertise
in sound-proofing and our in-depth knowledge in materials engineering, our engineers are continually developing innovative products to
meet our clients' stringent soundproofing requirements.
Bonnet - engine bay side—Megasorber FM25 (or FM12)
Megasorber D14: 2mm thick self-adhesive vibration damping
sheets. Line the metal panels: doors, roof, floor pan, wheel arches with our Megasorber D14 strips. Megasorber D14 has excellent damping
properties as well as unique adhesion properties. It will not delaminate from the substrate. D14 is widely used in automotive vibration
damping, metal roof rain noise reduction as well as in generator enclosures.
It is a proven product for many damping applications. D14 provides noise reduction over a wide temperature range.
Megasorber FM25: 25mm thick acoustic foam with fireproof sound
absorbing Soundmesh G8 facing. Line the door cavities, roof, under-bonnet with FM25.
Megasorber C14 (the Holden product) is specifically
designed composite for engine noise reduction. C14 consists of a high performance 12mm thick acoustic foam with black Soundmesh G8 facing
and a flexible high mass noise barrier with black non-woven backing. C14 increases transmission loss and provides sound absorption hence
maximizing noise reduction.
C14 can be glued onto substrates with Megasorber A200 or Megasorber A100 spray-on adhesives. Alternatively, a mechanical method of fixing can
be used such as pinning or the use of metal straps.
Application: Engine noise insulator
A client asked Megasorber to provide a product that sustains temperatures between -40°C to +140°C, can survive the tough engine-bay conditions
and meets a whole set of automotive specifications, such as the water-jet spray test.
Satisfied with the performance of the D14 range, our clients are looking into the possibility of using this product to soundproof roof panels,
door panels, wheel arch panels and many other areas on the automobile.
Megasorber D14 is also widely used as a heat shield due to its unique adhesion strength at elevated temperatures. As an automotive engineer has
stated, "It is always very handy to have Megasorber D14 around when you're working on your project" to reduce vibration.
