Advantages of polyester fiber sound-absorbing cotton products
Polyester fiber Sound-absorbing cotton does not contain harmful substances such as methanol and benzene.
Polyester fiber sound-absorbing cotton is a porous material with high sound-absorbing efficiency. It was tested at the Institute of Acoustics of Tongji University. The test result of thick products is R comprehensive noise reduction coefficient. If the density and thickness are increased, , there is still a lot of room for improvement of its performance
Good sound insulation performance, usually thick sound insulation cotton can meet the sound insulation requirements of ordinary occasions
Flame retardant polyester fiber sound absorption The cotton was experimentally tested in the National Fire Equipment Quality Inspection Center and reached Grade B in combustion performance of building materials
Price advantage, sound-absorbing cotton manufacturers sell directly, eliminating the profits of intermediate sellers.
The product is light, compact in structure, stable in shape, simple in construction, and can be cut at will
The product is harmless to the human body. No glue is added during the molding process, and different melting points are utilized. Fiber molding, experiments and practice have proven that it has no allergies to human skin, no pollution to the environment, and is odorless
It has good waterproof performance, strong drainage after water immersion, and no decrease in sound-absorbing performance. constant.
It can be used twice and does not cause secondary pollution to the environment.
