2013 laminated sound-absorbing PE foam - Jesion-D002

Jesion Low-frequency Acoustic Sheet is made by five layers of different thickness material.

1. The base is 3mm thick rubber sheet (NBR) as a liner. It separates the object with other layers in order to avoidvibration from the object.

2. Above the rubber sheet, there is a layer of 15 mil thick soft lead sheet, which is a high-density ultra-low frequency sound barrier material that can substantially attenuate low frequency sound waves. At the same time, the lead layer is effective to prevent radiation. Its thickness and softness makes it very easy to use on irregular and uneven surface.

3. Attached on the top of lead layer, it is a layer of 3mm thick polyethylene foam (PEF), which is a kind of high-efficiency foam with open and closed sound-absorbing cavity. It is very much suitable for absorbing low frequency sound waves. The opening cavity is to receive sound, and the closed cavity is to deplete the voice.

4. A layer of 6mm thick Polyurethane Foam (PU) is attached on the polyethylene foam. The PU foam is

environment-friendly material which could be degraded by itself. It has excellent sound-absorbing function due to its well-proportioned inner cavity structure.

5. The surface is 3 mil thick methyl urethane (PPU). Its surface is covered with random lines and it has strong tensile properties. As cover in outside, its main function is to protect the nether materials for extending the life cycleof the whole material, and to reduce sound reflection and significantly improve the system of sound-absorbing and thermal insulation performance. In addition, it is anti-dust, which makes the material very easy to be cleaned.

We choose fire-proof and environment-friendly material to make Jesion Low-frequency Acoustic Sheet. It can make sure healthy and safe. So it is widely used for car, yacht, medical devices, under cushion, back decoration board, inside sound box and other sites where much noise is to be reduced. Then it create safe and comfortable surroundings for people. Once it is used for car, it can make car audio do the best and to reduce of low-frequency fromroad noise. It also reduce the noise from engine and driveline. Since there is perfect sound barrier system by inside lead septum and other three layers material, Jesion low-frequency acoustic sheet is considered to be one of the best sound attenuation material. In order to get the best sound absorption and thermal insulation performance, we suggest you use it to gether with Jesion Sound-absorbing Sheet together.
