Home decoration special super soundproof cotton customized 100K bulk density formaldehyde-free environmental protection super coffee cotton soundproof cotton sound-absorbing cotton

To do sound insulation, choose the right sound insulation cotton, you can produce an effect

The material and bulk density determine the effect of the soundproof cotton

Material + Bulk Density = Effect

The "first-level sound absorption coefficient" is excellent, and the "second-level" effect is poor.

: The weight per cubic meter, which is related to density. With the same thickness, the higher the bulk density, the better the effect.

There are several common soundproofing foams on the market

Mineral wool, rock wool, glass wool, etc. are cheap, the pollution is very heavy, and the release of formaldehyde, benzene, and TVOC exceeds the standard...

First-class sound absorption coefficient, flame retardant grade A, soft and non-irritating material, very little dust, no formaldehyde and other releases, the highest 48K bulk density is low, and the original import price is high.

Cotton and linen fibers and animal hair, etc., have low bulk density, weak effect and high price.

Only the second-level sound absorption coefficient has low sound energy conversion efficiency and poor effect. The fire rating is low, and there are potential safety hazards.

The fibers used to make the fabric are coarse and elastic, and it is impossible to make a high density. It is easy to age, become brittle and fail.

The density of the rolled cotton is low, and the effect of controlling low-frequency noise is almost 0. The board cotton is very hard and elastic, resulting in a large gap between the cotton and the cotton, and the keel will be squeezed and deformed.

Is there any soundproof cotton with environmental protection and good effect at home?
