PET-CW-048-TC-814

100% polyester fiber (PET) is made of high-tech hot-pressing with cocoon cotton to achieve density and diversity which ensure ventilation. It becomes outstanding products of sound absorption and insulation materials products. Polyester fiber can be applied in a wide range of products. Its advantage includes decoration, Thermal insulation, environmental protection, light body, easy processing, stability, impact resistance, easy to maintenance. Sound absorption The sound absorption characteristics of polyester fiber sound-absorbing panels are similar to other porous materials, the sound absorption coefficient increases with the increase of frequency, and the sound absorption coefficient of high frequency .It is very large, and the cavity in the back and the space sound-absorbing body formed by it can greatly improve the sound-absorbing performance of the material. The noise reduction coefficient is roughly 0.8 ~1.10 or so, becoming a high-efficiency sound absorbing body in a wide frequen
