Polyester fiber sound absorbing panels (also known as glass wool) are called polyester fiber decorative sound absorbing panels. They are made of polyester fiber and glass fiber and are made by heat-pressing.

Material characteristics 100% polyester fiber is made by high-tech hot pressing and made of cotton shape to achieve density and ensure ventilation. It is an excellent product in sound absorbing and heat insulating materials. The highest sound absorption coefficient is 0.9 in the noise range of 125~4000HZ. In the above, according to different needs, the adjustment of the reverberation time is shortened, the sound impurities are removed, the sound effect is improved, and the clarity of the language is improved. The product has the characteristics of decoration, heat preservation, flame retardant, environmental protection, light body, easy processing, stability, impact resistance and easy maintenance. It can't be used as interior decoration. Its ingredients contain glass filaments. When dry, it will be confused in the air. The damage caused by inhalation is no less than PM2.5. Therefore, it is generally used in engineering noise reduction.
