Product Characteristics

Polyester Fiber Acoustic wool product advantages:

1: Environmentally-friendly polyester fiber sound-insulating cotton is made of 100% polyester fiber and is made of cocoon cotton after heat pressing. It is a new product developed in the past two years, completely replacing glass A new generation of new high-efficiency sound-absorbing materials such as fiber, rock wool, sponge and other harmful sound-absorbing materials. Now the country is also vigorously advocating the use of this kind of completely environmental protection, which can be in close contact with people (not itchy), harmless to the human body, and has strong sound absorption. Polyester fiber sound-absorbing cotton does not contain methanol, benzene and other harmful substances (glass wool, rock wool, mineral wool will volatilize methanol

2: high sound-absorbing efficiency, polyester fiber sound-absorbing cotton is a porous material, which is studied in Tongji University Acoustics The test result of 5cm thick products is NRC (comprehensive noise reduction coefficient): 0.80. If the density and thickness are increased, there is still a lot of room for performance improvement;

3: Good sound insulation performance, usually 5cm thick sound insulation cotton Meet the sound insulation requirements of ordinary occasions;

4: Flame retardancy: Polyester fiber sound-absorbing cotton is tested by the National Fire Equipment Quality Inspection Center, and reaches B1 level of building material combustion performance.

5: Price advantage, direct sales by manufacturers, eliminating intermediate sales The profit of the manufacturer can be delivered in Shenzhen.

6: The product is light, compact in structure, stable in shape, simple in construction, and can be cut at will;

7: The product is harmless to the human body, and no glue is added during the molding process. Fibers with different melting points are formed through experiments and practice. It has been proved that it has no allergies to human skin, no pollution to the environment, and no smell;

8: Good waterproof performance, strong drainage after water immersion, sound absorption performance does not decrease, and the shape remains unchanged.

9: It can be used twice, and there is no secondary pollution to the environment.

Since the polyester fiber sound-absorbing cotton is manufactured through a special process, it is composed of ultra-fine polyester fiber and has a three-dimensional network porous structure. The average fiber fineness can reach 1-2 microns or less. These advantages give environmentally friendly polyester fiber sound-absorbing cotton There are more interconnected pores. Under the action of friction loss, the sound energy is converted into heat energy, so that the sound is effectively suppressed. It also makes the environmentally friendly polyester fiber sound-absorbing cotton better than the existing glass fiber cotton, Rock wool and other materials.
