Metal felt F10 / F20 / F30

woolsound-absorbing

High Polymer Sound Insulation Felt High performance and high-quality polymer-metal sound insulation felt with excellent transmission loss. It is made of environmental protection materials and renewable polymer containing no halogen, thereby being green and environmental-friendly; it does not contain formaldehyde, benzene, asbestos, radioactive substances and other constituents harmful to the human body and does not contain substances depleting ozone, thereby fully meeting the international volatile organic compound emission standards. Description: High Polymer sound insulation felt has no material resonant frequency. The thin and high-quality material is stuck to the mechanical equipment shell and the engine room guard and can provide obvious noise control and vibration absorption data. The development of OFF metal damping and sound insulation felt meets the active sound insulation for the power cabins of industrial equipment and traffic equipment and the passive sound insulation acquirements for the carriage air noise and vibration. It can effectively absorb and obstruct the noise transmitted through the wall, the ceiling and the floor structure by fulling utilizing the mass law and damping principle of the architectural acoustic material. With the strong damping property and surface density, the sound reduction index of the raw material is greatly improved. OFF metal damping and sound insulation felt is compounded on the surfaces of the gypsum board, the wooden board, etc. to improve the sound reduction index of the raw material by 10-29 dB.
