Sound insulation felt


Sound insulation felt is now an excellent room insulation material on the market. Mainly used with gypsum board, used for wall insulation and ceiling noise insulation, also used in pipes, mechanical equipment noise and damping vibration. Sound insulation felt is not felt, which is completely different in appearance. Felt is light and soft, but sound insulation blanket is very thin but heavy. Sound insulation felt is refined by the tasteless EPDM rubber and a dozen organic minerals in accordance with a certain percentage. The product is black, environmental and no smell, which is a quite a good sound insulation material for the low frequency and high frequency sound and can effectively inhibit the propagation of various vibrations. The material thickness ranges from 1mm, 2mm, 3mm, etc. Inspected by the State Building Materials Bureau, the weighted volume is 3dB, 27dB and 30dB. The flexibility of the material is also very good, can easily bend, arbitrarily cut, which is the very convenient construction and fireproof soundproof material.


Sound insulation felt has the following advantages:


1.Material is light and ultra-thin;

2.Soft, high tensile strength.

3.Environmental protection, does not cause pollution for the environment;

4.Inhibit the propagation of low-frequency sound waves; excellent flame retardant properties.

5.Construction convenience.


Polyester fiber sound board:


It is an ideal indoor sound insulation material. Its raw material is 100% polyester fiber, which has sound-absorbing, environmental protection, fire-retardant, heat insulation, moisture proof, anti mildew, easy for dust removal, easy to cut, simple construction, good impact resistance, good independence and cost-effective advantages. There are a variety of colors to choose from, which can meet the different styles and levels of sound-absorbing decorative needs. Polyester fiber acoustic panels are mainly used in theaters, concert halls, museums, exhibition halls, library, interrogation room, gallery, auction hall, gymnasium, lecture hall, multipurpose hall, hotel lobby, hospital, shopping mall, school, piano room, conference room, studio , Recording room, KTV rooms, bars, industrial plants, room, home noise reduction and other places which have higher requirements on acoustic environment and high-end decoration.

Crest sound insulation sponge indoor acoustic material is a concave and convex wave shaped sponge formed by the special equipment. Its internal is filled with small voids and semi-open structure, which can absorb a lot of sound into the sound waves and play a decay effect on the sound waves, reduce the interference and reverberation of the indoor reflection, and improve the purity of the sound. Performance and characteristics are mainly:


1.High sound absorption

2.Good heat insulation

3.Flammable Class B1

4.Compact structure, stable shape

5.The weight is very light, the construction is safe and convenient

6.Harmless to the human body, no pollution to the environment and no smell

7.Water resistant, strong drainage after being flooded by water, sound-absorbing performance does not decline, and the shape doesn’t change.

8.Can be used twice, easy to destroy, no secondary pollution to the environment.
