The FDA Decorative Sound-absorbing Panel achieves customization of decorative panels through mold-casting techniques, allowing for tailored designs based on the requirements of designers. It can replicate complex decorative effects such as GRG/GRC, cultured stone, brick, natural rock layers, and more—effects that traditional sound-absorbing systems and acoustic materials cannot achieve. At the same time, it maintains physical and chemical properties comparable to those of these decorative materials.
