Advantages of environmentally friendly sound-absorbing cotton: odorless, does not contain any harmful substances, % environmentally friendly product, % recyclable, easy to use, easy to process, can be made into various shapes according to different needs, waterproof, moisture-proof, good breathability No additives or adhesives are added during the production process
The performance of environmentally friendly sound-absorbing cotton: high sound absorption rate and good sound insulation performance. The product does not contain formaldehyde and is harmless to the human body. It has been proven through many experiments that it is harmful to the human body. It has no skin allergies, no pollution to the environment, is odorless and waterproof, has strong drainage after being soaked in water, has no loss of sound-absorbing performance, can be used twice without changing its shape, is easy to destroy, and has no secondary pollution to the environment. It has a very good inhibitory effect on both low-frequency and high-frequency sounds, and can effectively inhibit the spread of various vibrations. It can be directly pasted on walls and ceilings without a protective surface, or can be directly filled as a built-in sound-absorbing and heat-insulating material. With high sound absorption rate and good sound insulation performance, polyester fiber sound-absorbing cotton is a porous material. It can cause sound to form a backflow in its cavity through the special high-density structure of the fiber, effectively achieving sound absorption and sound insulation functions. < car sound insulation cotton
