Polyester sound absorbing board is a sheet made of 100% polyester fiber. The sound absorber is highly designable and available in 48 colors. The shape can be arbitrarily cropped according to your needs.
The product production process does not discharge waste water and waste gas. The formaldehyde test of polyester fiberboard meets E0 standards.
Through proper construction and installation, tests have shown that its average sound absorption coefficient is 0.88 and noise reduction coefficient NRC is 0.95. It can reduce the echo in the room by about 80%. The thermal conductivity of polyester fiber is 0.037W/(mk), which can be used as a thermal insulation material.
