Custom Capabilities
MOQ: MOQ is 5.0 metric tons per specific gauge and color profile.
Color Matching Precision: In-house compounding delivers precision color matching to RAL or Pantone specifications under ΔE≤1.0.
Additive Customization: Formulations incorporate tin-based thermal stabilizers, organic UV blockers, and UL 94 V-0 self-extinguishing agents, allowing tailored performance for outdoor signage, transport interiors, and regulated fire-safety environments.
ESD Performance Tuning: Surface resistivity can be customized from 10⁹ to 10¹¹ Ω/sq, enabling controlled anti-static performance for electronics packaging, assembly environments, and cleanroom wall claddings.
Production Validation: A 50 kg pilot-line trial batch is available within 10 business days for formulation validation.
Packaging
- Fumigated wooden pallets support up to 2,500 kg, reinforced with 5mm thick L-shaped edge protectors.
- Multi-layer stretch wrap integrates heavy-duty desiccant packs to prevent maritime moisture absorption and water spotting.
- Standard 40ft HC containers accommodate up to 22 metric tons via 13–15 pallet configurations, or up to 25 metric tons via direct manual interlocking floor-loading.
Factory Technical Advantages
8 parallel twin-screw counter-rotating extrusion lines ensure a stable annual capacity of 18,000 metric tons for uninterrupted supply chains.
We have specialized in low-density expanded PVC extrusion for over 12 years, with dedicated formulation R&D for ESD and fire-safety grades added since 2017.
Long-term raw polymer supply agreements enable 6-month fixed-price rolling options for contract partners exceeding 100 metric tons annually.
The factory location, 50 kilometers from a deepwater container port, enables inland container drayage to the dock within 48 hours of production completion.
Compliance & Certifications
ASTM Fire Performance: ASTM E84 Class A certified with a Flame Spread Index (FSI) <25 and Smoke Developed Index (SDI) <450.
Heavy Metal Compliance: SGS certified free of lead, cadmium, mercury, and hexavalent chromium, fully compliant with REACH and RoHS directives.
Air Quality Safety: Formulated with zero urea-formaldehyde and zero detectable volatile organic compounds (VOCs) for indoor air quality safety.
Process Quality System: Extrusion parameters and cooling cycles are regulated under an ISO 9001:2015 audited system, ensuring thickness and density tolerances remain within ±0.05mm across batches.
FAQ
Q: Has this low-density board been used in actual ESD-controlled or cleanroom environments?
A: Yes, ESD-tuned formulations have been supplied to electronics assembly plants in Southeast Asia for anti-static wall cladding and packaging fixtures, with surface resistivity verified on-site after installation.
Q: What warranty applies if a delivered batch falls outside the stated density or thickness tolerance?
A: Buyers can file a claim with the batch record within 30 days of receipt, and confirmed non-conforming batches are replaced free of charge in the next production cycle.
Q: Can a buyer request a smaller sample of standard density and color before ordering the 5-ton MOQ?
A: Yes, standard 300×300 mm sample pieces in stock colors and gauges are available free of charge, typically shipped via courier within 5 business days.
Q: What third-party verification supports the mechanical and fire-performance claims of this board?
A: Every production shipment is accompanied by complete lab testing reports issued by SGS or Intertek. These documents include precise testing conditions, sample batch IDs, and QR codes linked directly to the official certification databases.
Q: How long does the board maintain stable performance under outdoor UV exposure?
A: With UV-stabilized formulations, service life in moderate climates generally ranges from 6 to 8 years before noticeable surface yellowing or mechanical degradation.
Q: Can the material maintain structural integrity under continuous load or fabrication stress?
A: Yes. Under CNC routing and standard fabrication conditions, the board typically retains dimensional stability without edge collapse when properly supported in panel framing systems.
