Quick answer
To choose a PET acoustic panel manufacturer in China, check six things before you compare prices:
- Is it a real factory, and which processes does it run in-house?
- Density (gsm) and thickness tolerance for each thickness.
- Fire and acoustic test reports: ASTM E84, EN 13501-1 and ISO 354.
- Stock colors, MOQ and lead time for standard and custom orders.
- Custom processing: CNC cutting, grooving, 3D molding, printing and fabric wrapping.
- Free samples, and how the factory keeps repeat orders consistent.
Jiadian is a PET acoustic panel factory in Changshu, Jiangsu, founded in 2013, with a production capacity of 8,000+ m² per day.
What should you check when comparing manufacturers?
China has a well-established supply base for PET acoustic panels, but the cheapest quotation is not always the best supplier. Use this checklist with every factory you compare. The right column shows Jiadian's own figures as an example of the answers to expect.
| What to check | Why it matters | Jiadian |
|---|
| Factory or trader | Direct production control matters for custom specs and repeat orders. | Own factory in Changshu, Jiangsu, since 2013 (see the factory) |
| Density (gsm) | Affects rigidity, machining and consistency. | 9 mm ≈1850 / 12 mm ≈2400 / 24 mm ≈3600 gsm (±3%) |
| Thickness tolerance | Important for CNC, grooving and assembly. | ±0.5 mm |
| Fire test reports | Requirements differ by market and application. | ASTM E84 Class A and EN 13501-1 B-s1,d0 for 9, 12 and 24 mm (test reports) |
| Acoustic test reports | NRC depends on mounting; check the test setup. | ISO 354: 12 mm NRC 0.85 with 200 mm air cavity, 0.4 mounted directly |
| Production capacity | Affects lead time and repeat-order reliability. | 8,000+ m² per day |
| Stock and MOQ | Distributors need short lead times and small orders. | 9 and 12 mm in stock, no MOQ; 24 mm made to order, MOQ 600 m² per color |
| Custom processing | Saves a second supplier for finished products. | CNC cutting and V/U grooving (Cut & Groove), 3D molding, printing, fabric wrapping, ceiling baffles |
| Samples | Check color, density and finish before ordering. | Free A4 samples and color cards, shipped in about 2 days (samples and shipping) |
What is a PET acoustic panel?
PET acoustic panels, also known as PET felt panels or polyester acoustic panels, are sound-absorbing panels made from polyethylene terephthalate (PET) fibers. They can combine recycled and virgin fibers. Jiadian panels are 100% polyester fiber with more than 75% post-consumer recycled PET.
Which thickness should you buy: 9 mm, 12 mm or 24 mm?
9 mm is lightweight and economical for wall panels and screens. 12 mm is firmer, with more machining options for CNC cutting, grooving, partitions and furniture. 24 mm gives the highest absorption and suits ceilings, baffles and thick wall panels. See the full comparison in How to choose 9 mm, 12 mm or 24 mm PET acoustic panels, or browse our PET felt sheets.
Stock colors or custom colors?
Stock colors are the better choice for distributors and projects that need short lead times, small quantities or repeat orders. Before ordering, confirm whether the supplier keeps finished panels in stock, or only produces standard colors after an order is placed.
Custom colors suit projects that must match a brand or interior reference. Because PET panels are made from colored fibers, not painted afterwards, custom matching starts at the fiber stage and needs a minimum raw-material quantity. Jiadian matches custom colors from physical samples: see Custom Color PET Acoustic Panels.
Manufacturer or trading company: how can you tell?
Ask which processes the supplier runs in-house: PET fiber processing, web forming, thermal bonding or hot pressing, panel cutting and post-processing. Factory videos, production records, quality-control procedures and an on-site or video audit help verify it.
A trading company is not automatically a bad supplier. What matters is whether your project needs direct production control, customization, technical support and consistent repeat production. More in Are you a manufacturer or a trading company?
What should you ask your supplier?
Can you keep specifications consistent across repeat orders?
For distributors and OEM customers, consistency matters as much as the first sample. Ask whether thickness, density, dimensions and surface finish stay the same in future batches.
How do you control color between production batches?
Projects supplied in phases may reorder the same color months or years later. Ask how the factory keeps color standards and production records.
What are the MOQ and lead time for standard and custom products?
Ask separately about stock colors, custom colors, special sizes and each thickness. Stock and made-to-order items usually differ.
Can you support long-term OEM orders?
For private label, check custom specifications, branded packaging, labels, color codes, batch identification and traceability.

Custom orders take about 14 days. 24mm panels are made to order and also take about 14 days. Lead time can vary with quantity and processing requirements, so our team will confirm it with your quote.
How to Choose 9mm, 12mm, or 24mm PET Acoustic Panels?
9mm, 12mm and 24mm are the three most common thicknesses you will see when sourcing PET acoustic panels. At Jiadian, one question we hear quite often from customers is: Which thickness should I choose for my project?
If acoustics are not your main concern and you are using PET panels mainly for decorative purposes, the choice is quite simple. You can choose the thickness that works best for your design and budget.
But if sound absorption matters, the answer becomes a little more complicated. I wouldn't simply tell you that a 24mm panel is better than a 9mm panel just because it is thicker. Thickness does affect acoustic performance, but it is not the only factor that matters. The GSM of the panel and installation method behind the panel and even how much of the space is covered in this room can all make a difference.
So rather than simply saying “24mm is better than 12mm,” it makes more sense to look at what you are actually using the panel for.
Quick answer from Jiadian: choose 9mm for wall panels and processed products on a budget, 12mm when you need a firmer panel for CNC cutting, grooving or furniture, and 24mm for ceilings, baffles or higher sound absorption. At Jiadian, 9mm and 12mm are in stock with no MOQ, and 24mm is made to order.
9mm PET Acoustic Panels
9mm is a very common thickness for PET felt panels, especially when the material will be used on walls or processed into finished acoustic products. It is relatively light and easy to work with. For many projects, the main reason for choosing 9mm is not that it needs to provide the highest sound absorption. It is because it gives a good balance between acoustic function, availability and budget.
We often see 9mm used for wall panels, decorative acoustic features, office applications, CNC-cut designs and V-grooved panels.
If you are buying PET sheets for further processing, 9mm is usually one of the first specifications worth looking at. Jiadian keeps 9mm panels in stock in 90 colors, with no MOQ.
What Changes When You Move to 12mm?
The difference between 9mm and 12mm doesn't sound like much. And they have the similar sound absorption effect. But once you have both panels in your hands, the difference is quite obvious. 12mm feels thicker and more rigid than 9mm.
So when should you choose 12mm? If you want a stronger and more solid panel, 12mm is usually a good option. At Jiadian, we see it used a lot in offices, meeting rooms, schools and other commercial spaces.
If you're choosing between 9mm and 12mm and don't know where to start, I would say 12mm is a very practical choice. It gives you more thickness and rigidity, but it's still easy to cut, groove and fabricate into different designs. Jiadian's 12mm panel is about 2400 gsm and is also kept in stock with no MOQ.
But I wouldn't say 12mm is always better than 9mm. If 9mm already works for your application, there is no need to pay for extra material you don't really need.
When Does 24mm Make Sense?
24mm is a different proposition. 24mm polyester acoustic felt can be useful when stronger sound absorption is required, such as
concert halls and theaters. And we often use 24mm PET acoustic felt as ceilings in commercial space because a thicker panel allows you to create more dimensional wall and ceiling features and gives the finished product a much stronger physical presence.
At Jiadian, we would normally look at 24mm when acoustic performance is a bigger part of the project requirement, or ceilings or when the design itself calls for a thicker material. But again, we would not recommend choosing 24mm simply because “thicker must be better.
For some projects, that would just add unnecessary material and cost. Jiadian makes 24mm panels to order, with an MOQ of 600 m² per color.
Does a Thicker Panel Always Absorb More Sound?
Generally, a thicker PET acoustic panel can provide better sound absorption, especially at certain frequencies. But I wouldn't compare two panels by thickness alone. How you install the panel matters a lot.
For example, take the same PET acoustic panel and install it in two different ways: one directly against the wall, and another with an air gap behind it. You may get very different acoustic results. So if sound absorption is important for your project, don't just ask the supplier: What's the NRC? Ask for the acoustic test report and take a quick look at how the panel was actually tested.
Was it installed directly against the wall or with an air gap? If there was an air gap, how deep was it? What thickness and GSM was the tested PET panel? These details matter. Jiadian's test reports state the mounting for each result: our 12mm panel reaches NRC 0.85 with a 200mm air cavity and 0.4 when mounted directly on the wall (ISO 354). Otherwise, you could be comparing two NRC numbers that were tested under completely different conditions.
9mm vs 12mm vs 24mm: A Quick Comparison of Jiadian Panels
| 9mm | 12mm | 24mm |
Typical GSM | Approx. 1850 gsm | Approx. 2400 gsm | Approx. 3600 gsm |
Material feel | Lighter | More rigid | Thick and substantial |
Wall applications | Yes | Yes | Yes |
Cutting & grooving | Yes | Yes | Yes |
Fire-retardant | Yes | Yes | Yes |
Often chosen for | Wall panels | Wall panels | Higher acoustic or ceilings |
One More Thing: Don't Ignore GSM
Thickness is easy to see, so naturally it gets a lot of attention. GSM is less visible, but it is worth checking.
Even if two panels are both 9mm thick, they may not actually be the same product when the weight is different.
For example, one supplier may offer a 9mm PET acoustic panel at 1850gsm, while another offers 1600gsm. That difference in GSM can affect the sound absorption, the material cost, and even how the finished panel looks after V-cutting processing.
You can see the difference more clearly when the panels are cut or grooved into patterns. A 1850gsm of 9mm PET panel has more material and usually gives you a denser, more solid finish. The cut edges and grooved patterns tend to look cleaner and hold their shape better than on a 1600gsm panel. So when you're comparing prices for 9mm PET acoustic panels, don't compare thickness alone. Always check the GSM as well. A cheaper 9mm panel may simply have less material in it. Jiadian's 9mm panel is 1850gsm (±3%).

A printed PET acoustic panel is a polyester fibre acoustic felt panel with a design printed directly on its surface. It absorbs sound like a plain panel, but carries a logo, pattern, photo or artwork.
At Jiadian, we print with UV ink. The ink is cured instantly on the felt surface, so the design sits on the panel itself rather than on a separate fabric or film.
This guide is for acoustic brands, traders and fit-out companies that want to source custom printed panels from a factory in China. It covers what we can print, the specifications, how to order, and lead times.
What can be printed on PET acoustic panels?
Almost any design can be printed, from brand graphics to natural textures:
Wood grain – oak, walnut and similar finishes, for a timber look without timber
Marble and stone – for receptions, hotels and retail interiors
Logos and brand graphics – in your brand colours, for offices and showrooms
Geometric and abstract patterns – for feature walls and creative spaces
Photos – landscapes, city views or your own images
Custom artwork – your own illustrations or designs
Wood grain designs printed on PET acoustic panels
Marble designs printed on PET acoustic panels
Send us the design, or describe the pattern you want, and we will check whether it suits printing.

Quick answer: A Class A fire rated acoustic panel has a flame spread index (FSI) of 0–25 and a smoke developed index (SDI) of 450 or less when tested to ASTM E84, the best of the three ASTM E84 classes. Our PET acoustic panel was tested by SGS to ASTM E84 with FSI 15 and SDI 25, and is also classified B-s1,d0 to the European standard EN 13501-1.
What does Class A fire rated mean?
ASTM E84 (also published as UL 723) is the North American tunnel test for the surface burning characteristics of building materials. A sample about 7.3m long is mounted on the ceiling of a tunnel and exposed to a gas flame for 10 minutes. Two numbers come out of the test:
Flame spread index (FSI): how fast flame travels along the surface, compared with reference materials.
Smoke developed index (SDI): how much smoke the material gives off while burning.
Building codes in the United States and Canada group the results into three classes:
| Class | Flame spread index | Smoke developed index |
|---|
| Class A (Class I) | 0–25 | 450 or less |
| Class B (Class II) | 26–75 | 450 or less |
| Class C (Class III) | 76–200 | 450 or less |
Class A is the classification most often required for wall and ceiling finishes in exits, corridors, schools, offices and other public interiors, which is why buyers ask for it first.
Our ASTM E84 result
| Standard | ASTM E84-24 |
| Laboratory | SGS |
| Report number | SDFTS25004023R02_EN (issued 21 July 2025) |
| Sample | Jiadian PET acoustic panel, 12mm |
| Flame spread index | 15 |
| Smoke developed index | 25 |
| Classification | Class A |
An FSI of 15 sits well inside the 0–25 Class A range, and an SDI of 25 is far below the 450 limit. You can verify the report number at check.sgsonline.com.cn. See all our reports on the PET acoustic panel test reports page.
ASTM E84 vs EN 13501-1: which one does your project need?
The two standards use different test methods, so one cannot be converted into the other. Use the one your project market asks for:
| ASTM E84 | EN 13501-1 |
|---|
| Used in | USA, Canada and many projects that follow US codes | EU, UK and many projects that follow European codes |
| Test method | Tunnel test, flame spread and smoke | SBI test (EN 13823) and small flame test (EN ISO 11925-2) |
| Best result for PET panels | Class A | B-s1,d0 |
| Our result | Class A (FSI 15, SDI 25) | B-s1,d0 |
What B-s1,d0 means
EN 13501-1 gives three parts in one classification:
B is the reaction to fire class. Classes run from A1 and A2 (non-combustible materials such as stone and mineral wool) through B, C, D, E and F. B is the best class an organic material like polyester fiber can normally reach.
s1 is the lowest smoke production class (s1, s2, s3).
d0 means no flaming droplets or particles during the test (d0, d1, d2).
Our EN 13501-1:2018 classification (SGS report SDFTS25004023R01_EN, 12mm sample, 2.40kg/m²) recorded FIGRA 25.2 W/s, THR600s 2.0 MJ and TSP600s 14.2 m², with no flaming droplets.
Fire rated vs non-fire-rated PET felt
Not every PET acoustic felt on the market is fire rated. Fire-retardant felt costs more to make and test, so a much cheaper quote may be for standard, non-fire-rated felt. When you compare suppliers, ask:
Is the quoted panel the fire-retardant version?
Which standard was it tested to, and which class did it reach?
Can you share the report number so I can verify it with the lab?
Which thickness and density was tested?
Our PET acoustic panel price guide explains how fire-retardant performance and other factors affect price.
Wording to use in specifications
Use precise terms such as fire rated, ASTM E84 Class A or classified EN 13501-1 B-s1,d0. Avoid fireproof or non-combustible: polyester fiber is a combustible material that has been tested and classified, and accurate wording helps your submittal pass review.
Our fire rated PET acoustic panels
Our 9mm, 12mm and 24mm PET acoustic panels come in 1220 × 2440mm sheets in about 90 standard colors, with 9mm and 12mm kept in stock. Custom shapes are available through CNC cutting and grooving and 3D molding.

In 2026, 9mm PET acoustic felt (2440 × 1220mm, about 1850gsm) from Chinese manufacturers typically sells for about USD 14–28 per sheet, or roughly USD 4.7–9.4 per square meter, EXW, in standard colors. 12mm panels (about 2400gsm) are typically USD 22–44 per sheet, and 24mm panels (about 3600gsm) USD 44–66 per sheet. Actual prices depend on GSM, quality, color, order quantity and trade terms.
PET acoustic felt prices in China
Most Chinese PET acoustic felt manufacturers offer three common thicknesses: 9mm, 12mm and 24mm. They are widely used for acoustic wall panels, offices, hospitality projects and further fabrication. The most common sheet size is 2440 × 1220mm (8 × 4 ft), which is about 2.98 m² per sheet.
| Thickness | Sheet size | Typical GSM | Market price per sheet | Approx. price per m² |
|---|
| 9mm | 2440 × 1220mm | about 1850gsm | USD 14–28 | USD 4.7–9.4 |
| 12mm | 2440 × 1220mm | about 2400gsm | USD 22–44 | USD 7.4–14.8 |
| 24mm | 2440 × 1220mm | about 3600gsm | USD 44–66 | USD 14.8–22.2 |
Price basis: general market reference for standard colors, EXW China. These are not fixed quotations and not Jiadian's own price list. Actual prices vary with quality, GSM, color, order quantity, fire-performance requirements, packaging and trade terms.
When comparing prices, remember that thickness alone does not define a PET acoustic panel. Two suppliers may both quote a 9mm panel, but one may offer 1600gsm while the other supplies 1850gsm. The higher-GSM panel uses more material per square meter, so it costs more to produce. Always compare thickness + GSM + sheet size, not just the price per sheet.
Why do PET acoustic felt prices vary between Chinese manufacturers?
Two panels with the same thickness, similar GSM and the same sheet size can still be priced differently. These are the main reasons.
1. GSM and material usage
GSM is the weight of material per square meter and is the easiest specification to compare. A 9mm / 1600gsm panel uses less material than a 9mm / 1850gsm panel, so it is usually cheaper. The lower GSM can also affect rigidity and how well the panel holds its shape after cutting or grooving.
2. Fire-retardant performance
Fire-retardant PET acoustic felt usually costs more than standard, non-fire-retardant felt, because of the extra cost of fire-retardant materials and fire testing. If your project needs a fire rating such as ASTM E84 Class A or EN 13501-1 B-s1,d0, make sure the quotation is for the fire-retardant version and ask the supplier for the test report. A noticeably cheaper quote may be for non-fire-retardant felt. See our own fire test reports.
3. Surface quality and production consistency
This is hard to judge from a quotation. Panels with similar specifications on paper can look quite different. Depending on the process and quality control, lower-priced panels may show:
uneven fiber distribution
small surface marks or spots
inconsistent surface texture
thickness variation
irregular edges
color variation between panels or batches
Before ordering, check real samples from the supplier.
4. Lead time and stock availability
A very low price looks attractive at the quotation stage, but delivery matters too. For project-based businesses, a delayed shipment can cost far more than the few dollars saved per panel. Suppliers that keep standard colors and specifications in stock can usually support small orders, urgent projects and repeat orders more easily.
5. Quality control and tolerances
Manufacturers apply different acceptance standards for thickness, dimensions, GSM, surface finish and color. Wider tolerances mean fewer rejected panels and lower production cost. Tighter tolerances need more precise production control and stricter inspection, which costs more. A lower price does not always mean wider tolerances. But if two quotes look the same on paper and the prices differ noticeably, ask: What are your tolerances for thickness, dimensions and GSM? This matters most for CNC cutting, V-grooving, modular wall systems and repeat production.
6. Brand premium
Well-known manufacturers may charge a brand premium that reflects their reputation, marketing and customer base. A higher price does not automatically mean better quality, and a lower price does not automatically mean worse quality. Compare the actual specifications, certifications and production capability behind each quote.
7. Service and support
Buyers also rely on the supplier for samples, color matching, quick replies, production updates, documents and logistics. Some suppliers invest more in this support, and it can show in the price. Evaluate service on its own, not from the price alone.

Samples
Can I get free samples?
Yes. A4 samples and color cards are free. We cover the cost of the samples, and the customer pays the shipping cost.
How quickly are samples sent?
Samples are usually sent out in about 2 days.
Which samples should I ask for?
Tell us the thickness and colors you are interested in, and any processing you plan to use, such as V-grooving or CNC cutting, UV printing or fabric wrapping. Browse our Color Catalog to choose colors before you request samples.
Payment
What payment methods do you accept?
We accept T/T (bank transfer).
How much deposit is required?
The deposit depends on the order. Please ask our sales team for the payment terms of your order.
Shipping
How are orders shipped?
We ship by sea or by air. Sea freight suits larger orders, while air freight is faster for small or urgent shipments.
Which port do you ship from?
Sea shipments leave from Shanghai port. Our factory is in Changshu, Jiangsu, near Shanghai.
How are the panels packed?
Every order is packed in four steps. Full sheets are counted and checked for colour, size and any other requirements you specify. Each stack is fully wrapped in PE film against dust and moisture. The stack goes into a strong corrugated carton cut to the panel size, so the sheets cannot slide. The carton is then taped on all seams and labelled with shipping marks and colour codes. Pallets are available on request.
Can you use our logo or our own shipping marks?
Yes. We can ship in plain brown cartons with no brand, which also suit distributors, or print your logo and product name on the carton.
Our standard label on every carton shows the product, thickness and size, colour code and quantity, N.W. / G.W. and carton number. We can use neutral marks without our factory name, or your own marks, for example your company mark, PO or item number, your label design or barcode, and the destination port and consignee.
Handling marks on the carton: keep dry, do not bend, lift with two people or a forklift, no heavy loads on the edge.
Container loading
How many PET acoustic panels fit in a 20GP or 40HQ container?
With loose cartons and no pallets, a 40HQ container holds 200 cartons and a 20GP holds 82 cartons of full-size 2440 × 1220 mm sheets. Loading on pallets makes unloading faster and safer, but fits slightly fewer panels.
| Container | Loading method | Cartons | 9mm sheets | 12mm sheets | 24mm sheets |
|---|
| 40HQ | Loose cartons (default) | 200 | 2000 | 1600 | 800 |
| 40HQ | Pallets: 4 large pallets + loose cartons | 192 | 1920 | 1536 | 768 |
| 40HQ | Pallets: 4 large + 4 small pallets + loose cartons | 180 | 1800 | 1440 | 720 |
| 20GP | Loose cartons (default) | 82 | 820 | 656 | 328 |
| 20GP | Pallets: 2 large pallets + loose cartons | 78 | 780 | 624 | 312 |
| 20GP | Pallets: 2 large + 2 small pallets + loose cartons | 74 | 740 | 592 | 296 |
Which loading method should I choose?
Loose cartons fit the most panels in a container. Pallets make unloading with a forklift faster and safer. The quantities above are for reference: a confirmed loading plan comes with every order.
