Uetersen glass fiber acoustic cotton uses natural ore as the main raw material, with some chemical raw materials melting into glass, in the melting state of li Yong centrifugal blowing process, blowing into flocculent fine fiber, fiber and fiber cross, winding each other, presenting many small gaps.  The fibers are fluffy and interlaced, and there are a lot of tiny pores, which are typical porous sound absorbing materials.  Glass fiber acoustic cotton can be made into wall panels, ceilings, space sound absorbers, etc., which can absorb a large amount of sound energy in the room, reduce reverberation time and reduce indoor noise.  When there is an air layer behind the glass wool, the sound absorption effect is similar to that of the glass wool with the same thickness without air layer.  In particular, the low-frequency sound absorption performance will be greatly improved than the solid stick on the hard board, and the sound absorption coefficient will increase with the increase of air layer thickness.  

Uetersen acoustic sound-absorbing sound insulation cotton, is a kind of centrifugal glass wool products with excellent acoustic and thermal insulation fireproof performance, it is produced by centrifugal method, will melt glass fibrosis and add environmental protection formula binder processing, with excellent sound-absorbing sound insulation, thermal insulation, fiber slender without slag ball,  It can be used in office, business, residential, hotel, conference and other buildings to create private, quiet and comfortable activity space for users.
