Polyester Acoustic Fiberboard Supplier in China

Polyester Acoustic Fiberboard: Engineered Acoustic Core Material from a Direct Manufacturer

As a specialized manufacturer of polyester acoustic fiberboard, we produce the fundamental engineered core material that powers high-performance sound absorption systems worldwide. Our thermally-bonded polyester fiberboard serves as the essential substrate for fabric-wrapped panels, perforated wood systems, and custom acoustic assemblies, offering designers and fabricators a versatile, sustainable, and high-performing alternative to traditional substrates like mineral wool or foam.

1. Core Technology & Material Composition

Our acoustic fiberboard is engineered from 100% polyester fibers, primarily utilizing recycled PET materials for an eco-conscious profile. Through a precise thermal bonding process—without chemical binders—we create a rigid yet workable board with a consistent, porous structure ideal for sound absorption.

• Superior Acoustic Properties: The uniform porous matrix effectively converts sound wave energy into negligible heat, providing excellent broadband sound absorption with a high Noise Reduction Coefficient (NRC) potential.

  
  

• Inherently Safe & Healthy: The board is formaldehyde-free, fiberglass-free, and emits zero VOCs. It is non-irritating and safe for handling and installation, promoting superior indoor air quality.

  
  

• Exceptional Physical Stability: Exhibits outstanding dimensional stability—it will not sag, shrink, or expand with humidity fluctuations. It is also moisture-resistant and inherently mold-resistant.

  
  

• Sustainable Foundation: Made with high recycled content, the board itself is fully recyclable at end-of-life, supporting circular economy goals and green building certifications.

  
  

2. Technical Specifications & Standard Data

As a manufacturer, we guarantee consistency through these controlled specifications:

• Standard Density: 40 kg/m³, 60 kg/m³, 80 kg/m³, 100 kg/m³ (custom densities available).

  
  

• Standard Thickness: 10mm, 15mm, 20mm, 25mm, 30mm, 40mm, 50mm.

  
  

• Standard Sheet Sizes: 1200 mm x 2400 mm, 1220 mm x 2440 mm, or custom-cut sizes.

  
  

• Fire Performance: Standard board meets Class B1 (DIN 4102). Can be upgraded to Class A (ASTM E84) with integrated fire-retardant treatment.

  
  

• Thermal & Acoustic Insulation: Also provides effective thermal insulation (λ ≈ 0.035 W/m·K).

  
  

3. The Direct Manufacturer Advantage for Fiberboard Supply

✅ Total Customization from the Production Line

We tailor the core material to your downstream fabrication needs:

• Precision Calendering: Control board thickness and surface finish to a precise tolerance.

  
  

• Custom Density Engineering: Develop specific density profiles to meet target acoustic performance (e.g., higher density for low-frequency absorption).

  
  

• Pre-Cutting & Shaping: Supply boards pre-cut to your required dimensions, CNC-routed into shapes, or die-cut for specific applications (baffles, cloud shapes, etc.).

  
  

✅ Rigorous Quality & Consistency Control

Our integrated manufacturing allows for strict batch-to-batch consistency. We perform in-house quality checks on density, thickness uniformity, rigidity, and fire performance to ensure every sheet meets specification.

✅ Cost-Effective Raw Material Supply

Purchasing the acoustic core board directly from our factory provides significant cost savings for panel fabricators and large projects. We offer competitive FOB or CIF pricing for container loads.

✅ Integrated Supply for Complete Solutions

As a manufacturer, we can also supply finished panel solutions. This vertical integration allows clients to source both the raw fiberboard and finished acoustic panels from a single, accountable partner.

4. Primary Applications & Fabrication Uses

Our polyester acoustic fiberboard is the ideal substrate for:

• Fabric-Wrapped Panel Systems: The primary core for wall and ceiling panels in offices, schools, and theaters.

  
  

• Perforated Panel Backing: Used as the sound-absorbing infill behind perforated wood, metal, or gypsum panels.

  
  

• Custom Acoustic Elements: Fabricated into free-standing baffles, hanging clouds, dimensional 3D shapes, and speaker enclosures.

  
  

• HVAC & Equipment Acoustic Treatment: Used as duct liner or machinery enclosure material due to its moisture resistance.

  
  

• DIY & Architectural Projects: Supplied to workshops and architects for custom, on-site acoustic builds.

  
  

5. Partnering with a Technical Manufacturer

Choosing our factory means accessing not just a product, but technical partnership. We provide:

• Comprehensive Technical Data Sheets (TDS) with acoustic test reports (e.g., ASTM C423).

  
  

• Sample Boards for your own fabrication and testing.

  
  

• Fabrication Guidance on cutting, gluing, and wrapping best practices.

  
  

• Logistical Support for reliable, palletized shipment of board materials globally.
