Key Features
Surface Hardness: Celuka co-extruded skin layer delivers Shore D hardness >45, ensuring clean edges without chipping during high-speed CNC routing.
Moisture Resistance: Water absorption <1.0% under ASTM D570 (24-hour immersion). Eliminates delamination and warping claims in marine cabinetry.
Fastener Retention: Screw pull-out force ≥1,300 N, maintaining joint integrity under continuous mechanical vibration and dynamic loads.
Thermal Stability: Linear thermal expansion coefficient of 6.5 × 10⁻⁵ mm/mm/°C, preventing buckling or joint separation in outdoor architectural cladding.
Customization & Secondary Processing
Color Matching: Strict Delta E <1.0 color tolerance control, calibrated to international RAL and Pantone systems.
CNC Machining: Factory pre-boring, routing, and edge profiling (tongue-and-groove, shiplap, chamfered) executed within ±0.5 mm tolerances.
Surface Finishes: Available in low-gloss matte, calibrated pore-free smooth, or wood-grain embossed finishes.
Lamination & Printing: Inline corona treatment guarantees surface energy ≥42 dynes for UV digital ink adhesion and direct bonding with HPL or wood veneers via PUR hot-melt adhesives. All sheets ship with double-sided 70 μm PE protective film.
Supply Support
Production Volume
8 automated twin-screw extrusion lines with a verified annual output of 20,000 metric tons, ensuring stable peak-season supply.
MOQ & Lead Times
MOQ is 2 metric tons for standard specifications and 10 metric tons per run for custom formulations. Standard production lead time is 14–21 days from order confirmation.
Logistics
Shipping available under FOB, CIF, and DDP terms, with pallet loading optimized per container to maximize volume utilization.
Compliance
Fire Retardancy: Certified to UL 94 V-0 (self-extinguishes within 10 seconds), ASTM E84 Class A (Flame Spread Index <25), and EN 13501-1 Euroclass B-s1, d0.
Chemical Safety: Manufactured with lead-free calcium-zinc stabilizers. Fully compliant with RoHS Directive 2011/65/EU and REACH SVHC standards.
Independent Verification: Third-party laboratory test reports and Technical Data Sheets (TDS) from SGS, Intertek, and TÜV Rheinland are available for every batch.
Traceability: Every shipped pallet carries a unique barcode linked directly to raw material batch logs and factory extrusion parameters for complete quality audit tracking.
FAQ
Q: How long can PVC Celuka Foam Sheet be used outdoors?
A: PVC Celuka Foam Sheet typically provides 8–10 years of outdoor service life under normal environmental conditions. For projects exposed to intense UV radiation, a UV-stabilized formulation is recommended.
Q: Will prolonged sunlight cause the sheet to fade or become brittle?
A: Standard white sheets maintain stable mechanical properties under normal outdoor exposure, while UV-resistant grades significantly reduce surface fading and chalking after years of direct sunlight.
Q: What warranty period and claims process apply to this Celuka foam sheet?
A: Standard products carry a 3-year warranty against manufacturing defects such as delamination or surface skin cracking, with claims submitted alongside batch barcode and photo evidence within 30 days of port arrival.
Q: Does the sheet require painting or additional surface protection for outdoor use?
A: No protective coating is required for most outdoor applications. However, applying an exterior-grade UV coating can further improve long-term color stability in regions with strong sunlight.
Q: Has this board been used in real HPL or wood veneer lamination projects at furniture manufacturing scale?
A: Yes, the corona-treated surface has been supplied to furniture panel laminators in East Asia for direct PUR hot-melt bonding with HPL, with no reported adhesion failure across multiple production runs.
Q: Is a smaller sample available for testing lamination or CNC routing performance before ordering the 2-ton MOQ?
A: Yes, sample pieces of 300×300 mm in standard thickness are available free of charge, typically dispatched via courier within 5 business days.
