Applications
Commercial Kitchen & Bathroom Cabinets: Moisture-resistant core boards for cabinet carcasses, vanity units, and wet-area furniture prone to high humidity.
Exhibition Displays & Signage: Calibrated substrates for direct UV digital printing, guaranteeing zero edge cracking during high-speed CNC routing.
Outdoor Wall Panels: Secondary exterior cladding components formulated with industrial-grade UV stabilizers to control color fading and cracking in high-UV exposure regions.
Concrete Formwork Alternatives: Reusable, moisture-resistant modular panels that increase cycle times and lower per-use costs compared to film-faced plywood.
Custom OEM & Formulations
Density Calibration: Adjustable foaming ratios from 0.40 g/cm³ to 0.85 g/cm³ to meet targeted mechanical load-bearing and weight-reduction specifications.
Co-Extrusion Layering: Dual-layer co-extrusion technology with an outer solid skin thickness ranging from 0.5 mm to 1.8 mm.
Custom Sheet Dimensions: Standard production widths at 1220 mm and 1560 mm. Programmable inline cross-cutting supports custom lengths up to 5800 mm.
Surface Finishing Options: Factory treatments including Raw Matte Calendaring, Double-sided Corona treatment (≥42 dynes) for adhesive bonding, HPL/CPL pressing, and vacuum PVC lamination.
Color Matching Accuracy: Compounding matched to international RAL and Pantone systems, maintaining a strict commercial tolerance variance within ΔE≤1.5 for batch-to-batch consistency.
Manufacturing Capacity
8 parallel twin-screw extrusion lines deliver an annual supply capacity of 20,000 metric tons, supporting stable, high-volume contract supply.
Inline laser gauging systems guarantee cross-board thickness variance within ±0.15 mm on standard 18 mm panels.
Computerized flying saws maintain sheet diagonal tolerance below ≤2.0 mm across a 2440 mm length.
MOQ is 5 tons for standard specifications and 10 tons for customized colors, with a standard production lead time of 15–25 working days from formal order confirmation.

FAQ
Q: What warranty period applies to WPC foam sheet, and what compensation is provided for confirmed defects?
A: Standard products carry a 3-year warranty against manufacturing defects such as delamination or core swelling, with confirmed defects compensated via free replacement sheets in the next shipment or a credit note against the original invoice.
Q: Has this board been used in actual commercial kitchen cabinetry or outdoor wall panel projects?
A: Yes, the moisture-resistant core has been supplied to 2 leading commercial kitchen cabinet OEMs in Vietnam and a major facade cladding contractor in Dubai. Our batch logs confirm zero swelling or delamination claims under continuous 90% RH (ambient humidity) and 50°C peak outdoor temperatures over a 36-month tracking period.
Q: How do you ensure consistent quality between different production batches?
A: Each production batch undergoes raw material inspection, online thickness monitoring, density verification, and final mechanical testing before shipment.
Q: What makes WPC Foam Sheet a better alternative to MDF or plywood?
A: Compared with MDF and plywood, WPC Foam Sheet provides water absorption below 0.5%, zero formaldehyde emission, and better resistance to humidity-related swelling.
Q: How do you verify the mechanical properties of each production batch?
A: Mechanical properties including tensile strength, flexural performance, and surface hardness are verified through standardized testing procedures based on ASTM test methods.
Q: What quality documents can you provide for commercial projects?
A: We can provide Mill Test Certificates, raw material traceability records, third-party compliance reports, and batch inspection documentation to support commercial construction and OEM procurement requirements.
