Anodized Aluminum Laminated PVC Foam Board is an engineered composite panel fabricated by bonding a hard, corrosion-resistant anodized aluminum sheet to a lightweight expanded polyvinyl chloride (PVC) core. The structure pairs the rigidity, abrasion resistance, and metallic finish of anodized aluminum with the low weight, moisture resistance, and thermal insulation of closed-cell PVC foam.
Bonding is executed using moisture-curing polyurethane reactive (PUR) hot-melt adhesive applied through industrial roll-coating systems, ensuring a permanent shear bond that withstands delamination across cyclical temperature ranges from -20°C to 80°C. Standard configurations feature single- or double-sided aluminum skins ranging from 0.3 mm to 1.0 mm bonded to PVC foam densities between 0.55 g/cm3 and 0.80 g/cm3.

Key Features
High Strength-to-Weight Ratio: Delivers structural rigidity comparable to thin solid aluminum sheets at less than 40% of the total assembly weight, reducing dead loads in transport and architectural installations.
Corrosion & Moisture Resistance: The closed-cell PVC core absorbs zero moisture, preventing core swelling, rotting, or fungal growth. The anodized aluminum layer forms an inert aluminum oxide barrier resistant to salt spray, humidity, and mild industrial acids.
Superior Surface Durability: Electrochemical anodization produces a hard, non-porous outer layer (surface hardness 300–400 HV) that resists scratching, fingerprint marking, and UV degradation without peeling or flaking.
Dimensional Stability: The balanced composite sandwich construction minimizes thermal warping, maintaining flatness across large surface spans under fluctuating ambient temperatures.
Machinability: Compatible with standard CNC routing, cutting, V-grooving, drilling, and mechanical fastening tools without edge chipping or core delamination.
Applications
Architectural Interiors & Cleanrooms: Wall partition panels, column wraps, cleanroom ceiling tiles, and modular laboratory furniture requiring sterile, chemical-resistant surfaces.
Transportation & Vehicle Outfitting: Interior ceiling liners, partition bulkheads, and cabinetry for railway coaches, commercial cargo vans, marine vessel cabins, and ambulances.
Signage & Display Fabrication: Dimensional architectural signage, museum exhibition booths, retail POS kiosks, and exterior directional paneling.
Industrial Enclosures: Machine safety guards, electrical control panel enclosures, and acoustical dampening panels.
Surface & Finish Options
Anodizing & Compliance Standards: Certified under Qualanod and EURAS architectural anodizing specifications, guaranteeing uniform oxide layer growth and corrosion resistance.
Anodizing Finishes:
Clear Satin (Silver) - EURAS EWAA/EURAS-NADETEF classification
Brushed / Hairline Silver
Electrolytically Colored Finishes: Champagne, Light/Dark Bronze, and Black (achieved via tin/nickel salt deposition for superior lightfastness).
Gloss Levels: Matte (10 - 20 deg), Semi-Gloss (30 - 40 deg), and Satin.
Protective Interleaving: Factory-applied laser-safe PE protective film on aluminum surfaces to prevent scratching during handling, CNC cutting, and mechanical fabrication.
OEM & ODM Customization
Dimensional Adaptation: Custom panel thicknesses, specific sheet widths, and non-standard lengths cut to drawing specifications to minimize on-site waste.
Skin-Core Combinations: Ability to laminate asymmetric panels (e.g., 0.8 mm thick aluminum on the front face, 0.4 mm on the rear face) or integrate high-density PVC foam cores (0.8 g/cm3) for high-load screw retention.
Edge Sealing & Profiling: Factory edge-banding with PVC/ABS extrusions or CNC milling of tongue-and-groove, ship-lap, and miter-fold joint profiles for direct modular assembly.
Pre-Fabrication: CNC routing of holes, cut-outs, and fastening slots based on CAD/STEP files provided by OEM engineering teams.
Quality Control
Raw Material Verification: Incoming aluminum coils undergo eddy-current testing for alloy composition (AA1050, AA3003, or AA6061) and coat-weight verification for oxide layer thickness (>= 15 um) via microscopic cross-section analysis. Foam core density and cell-structure uniformity are tested per ASTM standards.
In-Line Process Monitoring: PUR adhesive application weight is continuously monitored via gravimetric sensors. Nip-roll pressure and curing tunnel temperature profiles are logged in real-time to ensure consistent bond interface integrity.
Destructive Batch Testing: A 300 mm x 300 mm sample from every production lot undergoes 90-degree T-peel testing (ASTM D1876) and boiling water immersion tests (72 hours at 100°C) to verify bond permanence and prevent delamination under extreme moisture-heat exposure.
Dimensional Inspection: Finished panels are measured on a granite inspection table using laser distance meters and digital square gauges to verify length, width, diagonal squareness, and edge straightness.
