WPC sound-absorbing board is a composite functional board with wood fiber or bamboo fiber as the core sound-absorbing medium, combined with PVC resin, sound-absorbing cotton and antistatic coating. Through the high-density porous structure design (porosity ≥30%), it effectively absorbs medium and high-frequency sound waves (500Hz-4000Hz sound absorption rate ≥85%), and has moisture-proof, fire-proof and environmentally friendly characteristics. It is suitable for scenes with high acoustic requirements such as recording studios, theaters, and conference rooms. It is an upgraded substitute for traditional sound-absorbing cotton and mineral wool boards.

Professional acoustic venues​​​​

Recording Studio/Theater​​ : Porous structure + honeycomb design reduces reverberation time (T60≤0.8s) and improves sound clarity.​​

Concert Hall/Cinema​​ : Surface texture can adjust sound wave diffusion (diffusion coefficient ≥ 0.6) and optimize sound field distribution.

​​Commercial Space​​​​Hotel/Restaurant​​ : Sound absorption and noise reduction (NRC ≥ 0.8), reducing environmental noise interference (background noise ≤ 45dB).​​

Office/Meeting Room​​ : Anti-echo design (Speech Transmission Index STI ≥ 0.65) to improve speech clarity.​​

Public Facilities​​​​

Stadium/Airport​​ : Fire protection level B1 + sound absorption and noise reduction (weighted sound insulation Rw ≥ 35dB), in line with public safety standards.​​

School/Library​​ : Antibacterial and mildew-proof (antibacterial rate ≥ 99%), suitable for high-traffic environments.​​

Family scene​​​​

Children's room/study room​​: Rounded corner anti-collision design + low formaldehyde emission (≤0.03mg/m³), safe and environmentally friendly.

 

Highly efficient sound absorption​​

Porous structure (porosity ≥ 30%) + honeycomb layer design, mid-high frequency sound absorption rate ≥ 85%, NRC ≥ 0.8.

Surface texture can adjust the sound wave reflection angle and reduce echo interference (language clarity improved by 30%).​​

Multifunctional integration​​Fireproof B1 (flame spread time ≥ 30 minutes) + moisture-proof (water absorption expansion rate ≤ 0.3%), adaptable to complex environments.

Antistatic coating (surface resistance ≤ 1×10⁶ Ω), reducing dust absorption.​​

Diversified Design​​ It supports more than 10 surface effects including grooved wood grain, fabric texture, wavy grain, etc., taking into account both acoustic performance and decorativeness.​​

Easy installation​​ Clip-on/keel installation (no glue required), modular assembly, shortening construction time by 70%.

​​Environmentally friendly and durable​​

The material is 100% recyclable, the surface wear resistance reaches 10,000 revolutions (Taber test), and the service life is ≥15 years.

​​Intelligent Adaptation​​ Sensors or LED light strips can be integrated to achieve sound and light linkage (customized circuit required).

 

​Sound-absorbing structure design​​​​

Porous layer​​ : Wood fiber and sound-absorbing cotton are composited, with a porosity of ≥30% and a pore size distribution of 0.5-2mm to optimize sound wave absorption.​​

Damping layer​​ Add rubber particles (particle size 1-3mm) to improve low-frequency noise absorption (100Hz-500Hz sound absorption rate ≥75%).​​

Material Composite Process​​​​

Co-extrusion​​ : The PVC surface layer and the sound-absorbing core material are co-extruded at 180℃-220℃, and the thickness error is ≤±0.2mm.​​

Surface Grooving​​ : Laser cutting process, groove depth 1-3mm, groove spacing 5mm, enhanced sound wave diffusion.​​

Surface treatment technology

​​​​Fabric Texture​​ : Non-woven fabric lamination + hot pressing molding, air permeability increased by 20%, sound absorption efficiency increased by 15%.​​

Antistatic coating​​：Nano silicon dioxide coating, surface resistance ≤1×10⁶ Ω, dustproof and anti-static.​​

Quality Inspection​​​​Acoustic testing​​ ：ASTM C423 standard, NRC≥0.8, Rw≥35dB.​​

Environmental certification​​ Passed CARB certification, CE certification (EU), China Environmental Labeling (Ten-Ring Certification).

​​Special Process​​​​Edge sealing​​ : Ultrasonic welding technology prevents the sound bridge effect and improves the overall sound insulation performance.​​

Anti-mildew treatment​​ : Nano silver ion coating, antibacterial rate ≥ 99%, suitable for humid environment.
