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.
Great examples of such solutions include the soundproofing composite Megasorber FG12BK-B6R and our light-weight dampers Megasorber D14 and Megasorber LD5.
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.
Our engineers took up this challenge and a new product Megasorber FG12BK-B6R, a noise barrier plus acoustic foam with a fireproof sound-absorbing facing, was created. This soundproofing composite provides excellent sound absorption in the engine bay as well as blocking out engine noise in the cabin.
Our client is so happy with the performance of this product that they are discussing further applications, such as soundproofing the car boot and other areas.
Application: Firewall dampers
In response to automotive manufacturers' demands for lightweight damping materials, Megasorber has developed the D14 range of self-adhesive constrained-layer vibration-damping sheets which are thin and light-weight, yet highly effective. These products replace the traditional mass-dampers to reduce vibration.
RESULTS:
- cabin noise reduction
- increase sound transmission loss
Satisfied with the performance of the D14 range, our clients are looking into the possibility of using this product to dampen 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.
An alternative product is Megasorber LD5, a light-weight, water-based liquid deadener which can be sprayed, troweled or painted on.
Application: Moulded firewall insulator
Megasorber has tested a range of soundproofing composites to evaluate the effectiveness of each product to block out unwanted engine and road noise.
RESULTS:
- cabin noise reduction
- mould to shape
