Guangdong Yuefa Acoustic New Materials - Manufacturer of Sound Insulation and Sound Absorption Materials
Polyester fiber acoustic panels have emerged as one of the most effective sound absorption solutions in contemporary architectural and interior design. These innovative panels, composed primarily of recycled polyester fibers, combine exceptional acoustic performance with environmental sustainability. Unlike traditional acoustic materials like fiberglass or foam, polyester fiber panels offer superior durability, fire resistance, and design flexibility while maintaining excellent noise reduction coefficient (NRC) ratings between 0.7-0.95.
The global market for polyester fiber acoustic solutions has grown by 12.7% annually since 2020 (Acoustic Materials Report 2024), driven by increasing demand in commercial spaces, educational institutions, and entertainment venues. This growth reflects the material's advantages in sound absorption efficiency, eco-friendliness, and aesthetic customization compared to conventional alternatives.
100% Recycled PET fibers: Sourced from post-consumer plastic bottles (80-120 bottles per m² panel)
Thermal-bonded polyester matrix: No formaldehyde or volatile organic compounds (VOCs)
Fire retardant additives: Typically ammonium polyphosphate-based compounds meeting UL94 V-0 standards
The manufacturing process involves:
Fiber preparation: Shredding and cleaning recycled PET materials
Needle-punching: Mechanical bonding of fibers at 300-500 needles/cm²
Thermal curing: Heating to 180-220°C for structural stability
Surface treatment: Optional micro-perforation (0.8-1.2mm holes) for enhanced acoustics
This process creates panels with density ranges of 30-80kg/m³ and thickness options from 10mm to 100mm, allowing precise acoustic tuning for different frequency spectrums.

Integrated lighting: Pre-cut recesses for LED fixtures
Combining with:
Bass traps for low-frequency control
Diffusers for balanced acoustic environments
Fabric wraps for premium aesthetics
Google's London HQ achieved 42% noise reduction using 25mm polyester fiber panels with NRC 0.89, reducing employee distraction complaints by 67%.
MIT's Media Lab installed custom-shaped polyester acoustic elements that improved speech intelligibility from 72% to 89% in lecture halls.
Mayo Clinic's pediatric wards utilize antibacterial-treated polyester panels that reduce noise levels below 35dB (WHO recommendation) while being easily sanitized.
