The acoustic panel or sound-absorbing insulation panel is made of 100% polyester fiber by non-woven via pressing. The sound-absorbing decorative art panel has strong plasticity and can be cut according any requirements, with good sound-absorbing performance. Through proper construction and installation, the average sound absorbing coefficient is 0.88, and the noise reduction coefficient is NRC = 0.95. The safety is good. No chemical is added to the production process , so there is no toxic product release; good environmental protection performance, the raw material of this product is 100% polyester fiber, which can be completely recycled; good heat preservation effect, the thermal conductivity of polyester fiber is 0.037w / (m·K), which can be used for heat preservation and insulation.
