Environmentally friendly sound-absorbing cotton is made of polyester fibers that are stacked and bonded by hot pressing. It is in direct contact with human skin and will not produce any harmful effects. It is a non-toxic, harmless and non-toxic material. Pollution-free new sound-absorbing materials. Advantages of environmentally friendly sound-absorbing cotton: It is odorless, does not contain any harmful substances, is an environmentally friendly product, is recyclable, is easy to use, and can be made into various shapes according to different needs. It is waterproof, moisture-proof, and has good breathability. No additions are made during the production process. The performance of environmentally friendly sound-absorbing cotton with any additives and adhesives, 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 does not have any allergies to human skin and does not pollute the environment. , odorless and waterproof, with strong drainage after being soaked in water, the sound-absorbing performance does not decrease, the shape remains unchanged and can be used twice, it is easy to destroy, and there is 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.
