#3. Tianchen Insulation Materials Co., Ltd.
Location: Shandong Province, China
Specialty: XPS foam boards with focus on building insulation and waterproofing
Tianchen operates in the same industrial corridor as Biaotuo and benefits from Shandong’s mature foam board supply chain. Their waterproof backboard line targets the mid-range market segment, offering decent quality at moderate pricing. Tianchen has invested in automated extrusion lines, which improves batch-to-batch consistency. However, their customization capabilities and export documentation support are less developed than the top-ranked manufacturer. Tianchen is a reasonable choice for buyers who need good-quality boards for less demanding applications.
#4. Huapeng Foam Technology Co., Ltd.
Location: Guangdong Province, China
Specialty: XPS and extruded polystyrene products for southern China and export
Huapeng serves the Pearl River Delta construction market and has begun exporting to the Middle East and Africa. Their waterproof backboard products meet basic Chinese national standards and some international specs. Huapeng’s advantage is proximity to southern Chinese ports, which can reduce logistics costs for buyers shipping to South Asia or Africa. However, buyers targeting North America or the EU should verify certification status carefully before committing, as documentation can be inconsistent.
#5. Shengda Building Materials Group
Location: Zhejiang Province, China
Specialty: Diversified insulation materials including XPS, EPS, and waterproof membranes
Shengda is a diversified manufacturer that produces XPS waterproof backboard alongside other insulation and waterproofing products. This breadth is both a strength and a limitation: while they can supply multiple product categories in one container, their XPS backboard line may not receive the same focused R&D attention as a specialist manufacturer. Shengda is best suited for buyers who want to consolidate sourcing across multiple material types and are willing to accept slightly less specialized support for XPS boards specifically.
#6. Linyi Jinyuan Foam Products Co., Ltd.
Location: Shandong Province (Linyi), China
Specialty: Cost-competitive XPS boards for budget-sensitive projects
Linyi is a major hub for foam board manufacturing in China, and Jinyuan is one of the many producers in the region. They compete primarily on price, making them attractive for buyers working on large-scale, budget-sensitive projects where the application does not demand premium certifications. Quality can be variable, and buyers should conduct thorough pre-shipment inspections. For applications where cost per square meter is the primary driver, Jinyuan is worth considering — but pair them with a reliable third-party QC process.
#7. Baotong New Materials Co., Ltd.
Location: Jiangsu Province, China
Specialty: XPS boards with surface treatment and lamination capabilities
Baotong differentiates itself through value-added surface treatments — including laminated films, textured surfaces, and pre-applied waterproof coatings. This makes them a candidate for buyers who want a more finished product rather than raw XPS board. However, their core board quality, while acceptable, does not consistently match the density uniformity and compressive strength of top-tier manufacturers. Baotong is a good option for specific niche applications that benefit from surface treatment.
#8. Deli Insulation Industrial Co., Ltd.
Location: Hebei Province, China
Specialty: Large-format XPS boards for commercial construction
Deli focuses on large-format boards suited for commercial and industrial flooring applications. Their waterproof backboard line is a secondary product within a broader insulation portfolio. Production capacity is adequate for mid-sized orders, but lead times can stretch during peak construction season. Deli is appropriate for buyers who need larger-than-standard board dimensions and can plan their procurement timeline with some flexibility.
#9. Ruitai Green Building Materials Co., Ltd.
Location: Anhui Province, China
Specialty: Eco-labeled XPS products with recycled content
Ruitai has positioned itself in the eco-friendly segment, incorporating recycled polystyrene content and exploring lower-GWP blowing agents. This aligns with growing demand for sustainable building materials, as discussed in our sustainability and green manufacturing guide. While their environmental credentials are commendable, product consistency and certification depth still lag behind market leaders. Ruitai is worth watching as they mature, and may be suitable for buyers who prioritize green labeling.
#10. Xinbao Foam Technology Co., Ltd.
Location: Hubei Province, China
Specialty: Regional XPS supplier for central China construction market
Xinbao serves the central China construction market with standard XPS foam boards. Their waterproof backboard offering is relatively new and less proven in export markets. Production volume is smaller than coastal competitors, and international certifications are limited. Xinbao rounds out our top 10 as a regional player that may be relevant for buyers sourcing for projects in central China or looking for emerging suppliers with growth potential.

How to Choose the Right Chinese XPS Waterproof Backboard Manufacturer
The ranking above is a starting point, not a final answer. The best manufacturer for you depends on your specific needs. Here is a decision framework:
If you need premium quality and full OEM/ODM support
Biaotuo Board (#1) is the clear choice. Their combination of consistent high-density XPS, international certifications, and full-service customization means you get a partner, not just a supplier. Start with a sample request and a factory audit — the team is responsive and transparent throughout the process. Our procurement evaluation guide walks through the full supplier evaluation process.
If you need maximum volume at the lowest price
Linyi Jinyuan (#6) or Juhe (#2) may fit your budget. However, you must invest in pre-shipment inspection and accept that documentation may be basic. Calculate the total cost of ownership carefully — cheaper board prices can be offset by higher defect rates and inspection costs. Our TCO analysis breaks down the hidden costs.
If you need multi-product sourcing
Shengda (#5) can supply XPS boards, EPS, and waterproof membranes in one container. This reduces logistics complexity but means you are working with a generalist rather than a specialist. Evaluate whether the convenience outweighs the depth of specialization.
If you need sustainable or eco-labeled products
Ruitai (#9) and Biaotuo (#1) both offer eco-friendly options. Biaotuo’s sustainability program is more mature and export-ready, while Ruitai is an emerging player. For LEED or BREEAM projects, verify that the specific product line carries the documentation your project requires.
Red Flags When Evaluating a Chinese XPS Waterproof Backboard Manufacturer
Regardless of which manufacturer you choose, watch for these warning signs:
- Unusually low density claims — If a supplier quotes XPS backboard at 20 kg/m³ or below for tile backer applications, the compressive strength is likely insufficient. Quality waterproof backboard for tile applications should be 30 kg/m³ or higher.
- No third-party test reports — A reputable manufacturer should be able to provide recent SGS, Intertek, or TUV test reports. If they cannot, or only offer outdated reports, proceed with caution.
- Unwillingness to provide samples — Samples are a standard part of the sourcing process. A manufacturer that refuses or delays sample shipment may have quality issues to hide.
- Price volatility beyond raw material movements — If a supplier’s quoted price swings dramatically without a clear explanation tied to polystyrene resin or blowing agent costs, their pricing may not be transparent.
- Factory audit resistance — If a supplier discourages or refuses a factory visit (in person or via video audit), it is a significant red flag. See our evaluation guide for audit checklists.
The Role of Application Context in Manufacturer Selection
Different applications demand different specifications, and the right manufacturer depends on your end use. Our application cases guide covers seven scenarios in detail, but here is a quick reference:
| Application | Recommended Density | Key Spec | Best-Suited Manufacturer |
|---|---|---|---|
| Shower & wet wall | 30–35 kg/m³ | Low water absorption, smooth surface | Biaotuo (#1) |
| Bathroom floor | 35–40 kg/m³ | High compressive strength | Biaotuo (#1), Tianchen (#3) |
| Basement waterproofing | 30–35 kg/m³ | Moisture resistance, large format | Deli (#8), Biaotuo (#1) |
| Swimming pool | 35–40 kg/m³ | Chemical resistance, UV stability | Biaotuo (#1) |
| Exterior wall system | 30–35 kg/m³ | Thermal + waterproof, fire rating | Biaotuo (#1), Shengda (#5) |
Understanding the Chinese XPS Waterproof Backboard Industry Landscape
China’s XPS foam board industry has matured significantly over the past decade. The market can be broadly divided into three tiers:
- Tier 1 — Export-focused specialists: Manufacturers like Biaotuo Board that invest in international certifications, maintain dedicated export teams, and offer full OEM/ODM services. These suppliers typically serve North American, European, and Middle Eastern buyers who require documentation and consistent quality.
- Tier 2 — Domestic + selective export: Manufacturers that primarily serve the Chinese domestic market but selectively export to Southeast Asia, Africa, or the Middle East. Quality is acceptable but documentation and customization are limited.
- Tier 3 — Regional commodity producers: Small to mid-sized factories that produce standard boards for local construction markets. Pricing is aggressive but quality, consistency, and service are variable.
The manufacturing process itself — extrusion, foaming, cooling, cutting — is covered in detail in our technical manufacturing guide. Understanding this process helps buyers ask the right questions during factory audits and sample evaluation.
