3D Thermoformed PET Felt Acoustic Wall Panel
Consistent Supply · Clear Specifications · Long-Term Cooperation
3D thermoforming PET panels are not just decorative elements.
They require stable base density, consistent thickness tolerance, and structural integrity to avoid deformation after pressing.
We manufacture high-density PET felt panels specifically optimized for high-temperature molding.
Material: Ecofriendly recycled PET from waste bottles
, 100% PET(polyester fiber)
Technology: 3D thermoforming/high-temperature pressing
Size: 300x300mm
Color: 58options available
Mold: current existing mold
Application: School, kindergarten, library, meeting rooms, office, home-theaters, musical studio, hotel, restaurant, etc.
Material
use PET felt panel made from high-density polyester fibers, primarily derived from 100% recycled waste PET bottles.
Unlike mineral wool or fiberglass, PET felt panel does not release airborne fibers, making it safer to handle, to cut, and to install.
Fiber melting point (around 240°C)
Formaldehyde-free
VOC emission level (E0 level if applicable)
Sound absorption coefficient range
Colorfastness grade
The mostly used is 9mm and 12mm thickness PET felt panel to make 3D thermoforming panels.
What Makes 3D Thermoforming Different from Standard PET Panels?
Not every PET felt panel can be thermoformed successfully.
3D thermoforming is a structural process, not just a surface design upgrade. During high-temperature pressing, the panel undergoes controlled compression of up to 40–60%. If the base density is unstable or the fibers are unevenly bonded, the result can be surface cracking, deformation, edge fraying, or dimensional inconsistency after installation.
Standard flat PET panels are designed primarily for sound absorption. In contrast, 3D molded PET acoustic panels must deliver three things at once: structural integrity, precise geometric definition, and reliable acoustic performance. The base material must maintain uniform density, stable thickness tolerance, and sufficient rigidity to ensure sharp edges and accurate module alignment on large feature walls.
This is why thermoforming quality is determined long before molding begins — it starts with the raw panel manufacturing capability. A properly engineered base panel ensures stable shape retention, clean finishing, and long-term durability in commercial environments.
Product Specifications
thickness range: 3mm-6mm after high temperature pressing.
Base thickness before thermoforming: 9mm / 12mm
Final thickness after pressing: approx. 3–6mm (depending on mold depth)
Compression ratio: 40–60%
Density: 2000g/m² (9mm reference), 2400g/m² (12mm reference)

Technical data: Fire Rating
Our PET felt panels comply with international fire safety standards:
- EN 13501-1 (B-s1, d0) – European market
- ASTM E84 (Class A) – North America
- BS 476 Part 6 & 7 – UK projects
- SGS test reports available
For thermoformed 3D panels, fire rating remains unchanged after molding because the base material is homogeneous solid fiber — not surface-treated foam.
Technical data: NRC value
Acoustic performance depends on installation method.
3D structured surface improves sound diffusion performance, not only absorption.
Available:
- Reverberation chamber test reports
- Project acoustic simulation support

Typical Applications:
- Retail brand display walls
- Exhibition booth structures
We support:
- Shop drawing coordination
- Installation method suggestion
FAQ
Q1: Can 3D thermoforming crack during transport?
No. Panels are flexible but structurally stable. Proper packaging avoids deformation.
Q2: Will the shape change in humid environments?
PET fiber is moisture-resistant. Dimensional stability tested.
Q3: Can I customize my own 3D mold?
Yes. We support custom mold development for project orders.
Q4: Can you produce small trial quantity?
Yes. Sample development available.
Q5: Is glue required for installation?
Depends on design. Options: construction adhesive, Z-clip, aluminum frame system.
