Polyester fiber sound-absorbing panel

Polyester fiber sound-absorbing panel is a sound-absorbing material made of 100% high-density polyester fiber, which is widely used in interior decoration and acoustic treatment. It is known for its environmental protection, lightness, easy processing and good sound absorption properties. It is one of the common acoustic materials in modern buildings, home decoration and work spaces.

1. Characteristics of polyester fiber sound-absorbing panels
1. Good sound-absorbing effect: Polyester fiber sound-absorbing panels have a porous structure, which can effectively absorb sound waves, reduce echo and noise, and have a significant absorption effect on medium and high-frequency sound waves.
2. Environmentally friendly and non-toxic: The material is made of recyclable polyester fiber, has no harmful chemical components, complies with environmental protection standards, is non-toxic and odorless, and will not cause harm to human health.
3. Fire retardant: Polyester fiber sound-absorbing panels have been specially treated and have certain fire retardant properties, usually reaching B1 level flame retardant standards.
4. Beautiful and diverse: The surface of the sound-absorbing panels can be made into a variety of colors and textures, which can meet the needs of different decorative styles, and is easy to cut, splice, and install.
5. Strong durability: Polyester fiber material has strong aging resistance, is not easy to deform, does not fade, and has a long service life.
6. Lightweight: Compared with other sound-absorbing materials, polyester fiber sound-absorbing panels are lightweight and easy to transport and install.

2. Parameters of polyester fiber sound-absorbing panels
1. Density: 120-200 kg/m³. The higher the density, the better the sound absorption effect, but the hardness of the board will also increase.
2. Sound absorption coefficient: 0.75-0.95 (NRC value). The higher the NRC value, the better the sound absorption effect. Generally, polyester fiber sound-absorbing panels have excellent sound absorption performance in the 500Hz~4000Hz frequency band.
3. Thickness: 9mm, 12mm, 15mm, 24mm and other different thicknesses are available. The thicker the thickness, the better the sound absorption performance, especially the better low-frequency absorption effect.
4. Size: Common specifications are 2440mm×1220mm. Customized cutting can be done according to actual needs.
5. Fire protection grade: B1 level (flammable material). In practical applications, different fire protection treatments can be selected according to different occasions.
6. Tensile strength: >3.5 MPa. Sound-absorbing panels have high mechanical strength and tensile properties.
7. Moisture resistance factor: 50-100. The board can maintain good stability in a humid environment and is not easily deformed by moisture.
8. Thermal insulation performance: The thermal conductivity is generally about 0.035 W/m·K, which has a certain thermal insulation effect.

3. Application areas of polyester fiber sound-absorbing panels
1. Conference rooms and office spaces: used to absorb noise, reduce reverberation, and improve speech clarity and work efficiency in conference environments.
2. Home theaters and concert halls: Provide a high-quality acoustic environment, reduce echoes and unnecessary sound wave reflections, and improve sound quality.
3. Recording studios and broadcasting rooms: effectively absorb noise in recording or broadcasting, improve sound quality, and ensure clear and pure sound.
4. Public places (such as airports and stations): Reduce crowd noise and create a quieter environment.
5. Classrooms and training centers: Reduce environmental noise and help improve teaching effectiveness and student concentration.

4. Installation and maintenance
Polyester fiber sound-absorbing panels are easy to install. They can usually be directly attached to the wall with glue or fixed through a keel frame. The panels are lightweight, easy to cut, and suitable for spaces of all shapes and sizes. Due to its strong durability, it requires almost no special maintenance and only requires regular dust cleaning during daily use.

Summarize
Polyester fiber sound-absorbing panels have become one of the preferred materials in modern acoustic decoration due to their excellent sound absorption effect, environmental protection and ease of use. Whether it is a commercial environment or home decoration, it can effectively improve the acoustic performance of the space and provide people with a quieter and more comfortable living and working environment.
