Easy Cutting Fire Resistance Sound Insulation and Damping Felt

Metal damping and sound insulation felt is a high performance and high quality polymer metal sound insulation felt with excellent transmission loss. It is made of 90% high purity fine iron powder and renewable polymer containing no halogen, thereby being green and enviranmental-friendly;

it does not cortain 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.

metal damping and sound insulation felt has good tire resistance, heat resistance, elasticity flexibility and tensile strength. It can be cut with the wallpaper cutter, the scissors and other tools, or be fixed with the code nails or adhesive for building sound insulation, and the OFF Metal damping and sound insulation felt for the mechanical equipment can be matched with the sheet.

Metal through the staple bolt or adhesive. OFF metal damping and sound insulation felt is the intcgrated matcrial which is easy to construct and is not limited by shape, structurc and space.

Metal damping and 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.

Metal damping and sound insulation felt 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 malerial. 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
