Sound absorbing centrifugal glass wool
The glass wool adopts the acoustic principle of microporous design, which makes the sound wave transferred into the microporous tube to be converted into kinetic energy and dissipated, isolated and transmitted. The slag ball content is low, the fiber is long and thin, effectively imprisons the air, makes it unable to flow, and eliminates the convective heat transfer of the air
