Our polyurethane partition panels consist of a high-density rigid polyurethane (PUR) or polyisocyanurate (PIR) foam core bonded between two pre-painted galvanized steel facings. Designed specifically for interior space separation in controlled environments, the modular tongue-and-groove joint system ensures rapid installation and superior sealing against air, moisture, and particulate infiltration.
Core Material: Rigid Polyurethane (PUR) / Polyisocyanurate (PIR)
Standard Thicknesses: 50mm, 75mm, 100mm, 150mm
Standard Width: 950mm, 1150mm (modular effective coverage)
Length: Cut to project specifications up to 12 meters

Key Features
High Thermal Resistance: Closed-cell ratio exceeding 95% minimizes thermal bridging and maintains strict temperature gradients in climate-controlled spaces.
Structural Stability: High compressive and bending strength allow for vertical self-supporting partition walls up to 6 meters without intermediate steel columns.
Airtight Joint Engineering: Precision-milled tongue-and-groove profiles accept silicone or gasket seals to prevent air leakage in cleanrooms and positive-pressure labs.
Fungistatic & Inert Surface: Non-porous facings resist microbial growth, chemical cleaning agents, and repeated sterilization cycles.
Applications
Pharmaceutical Cleanrooms: ISO Class 1 to 8 facilities requiring flush wall surfaces and zero particle shedding.
Cold Storage & Freezers: Temperature-controlled chambers operating from 0°C to -40°C.
Food Processing Plants: USDA/Hygienic processing areas requiring frequent high-pressure washdowns.
Modular Data Centers & Offices: Rapid deployment interior divisions requiring integrated cable raceways and fire compartmentalization.
Surface & Finish Options
Panel facings can be customized to match chemical resistance, aesthetic, and durability requirements of specific industrial environments.
Standard Polyester (PE): 25-micron coating for general industrial partitions.
Polyvinylidene Fluoride (PVDF): Superior UV and chemical resistance for aggressive washdown areas.
Silicon Modified Polyester (SMP): Enhanced scratch and abrasion resistance for high-traffic corridors.
Stainless Steel Facings: Grade 304 or 316, 0.5mm thickness, for pharmaceutical and sterile environments.
Customization Capabilities
We process custom orders based on engineering shop drawings:
Embedded Conduits: Integrated PVC or metal conduits for electrical wiring and gas piping.
Non-Standard Lengths: Exact cut-to-length manufacturing to eliminate on-site trimming waste.
Reinforced Inserts: Wood or steel internal framing embedded at hardware attachment zones (door frames, window cutouts, equipment hanging points).
Corner Panels: Factory-molded 90-degree internal and external corner units to eliminate field-joint flashing.
Manufacturing & Quality Control
Continuous Double-Belt Line: Automated high-pressure foam injection and heated lamination ensure uniform foam density and prevent panel delamination or bowing.
Raw Material Verification: Polyol and isocyanate ratios are computer-monitored via automated metering pumps. Steel coils undergo incoming thickness, yield strength, and coating adhesion testing.
Dimensional Inspection: Laser-guided cutting systems maintain panel squareness tolerance within ± 1.0 mm and thickness tolerance within ± 0.5 mm.
Traceability: Each production batch is assigned a unique barcode linked to raw material mill test reports and density logs.
Installation & Joint System
Tongue-and-Groove Interlock: Panels slide together sequentially, secured via hidden cam-locks or through-fastened structural clips fixed to floor and ceiling tracks.
Accessory Integration: Compatible with aluminum extrusion coves, drop-ceiling hangers, and flush-mounted cleanroom doors and viewing windows.
Thermal Break Details: Elimination of metal-to-metal contact points across the panel core prevents condensation buildup on cold-side surfaces.
Packaging & Logistics
Protective Interleaving: PE protective film applied to both exterior surfaces; high-density foam spacers placed between stacked panels to prevent scratching during transit.
Export-Grade Crating: Bundles secured with heavy-duty steel strapping and wrapped in waterproof woven polyethylene membrane. Palletized for forklift or crane offloading at job sites.
Loading Optimization: Standardized bundle dimensions designed for 40-foot High Cube (40'HC) containers and open-top flat racks to minimize ocean freight costs.
Standard Production Lead Time: 15 to 20 business days upon shop drawing approval and deposit receipt.
Frequently Asked Questions
Q: What is the maximum unsupported span for these partition panels?
A: Depending on wind or pressure loads and panel thickness (100mm), vertical partition walls can span up to 6.0 meters without supplementary steel girts. For negative/positive pressure cleanrooms exceeding this height, intermediate structural framing is required.
Q: Are these panels compliant with FM Global insurance standards?
A: PIR core formulations are available with FM 4880 Class 1 fire classification. Please specify fire rating requirements during initial inquiry so corresponding test certificates and material specifications can be provided.
Q: Can cutout openings for doors and windows be factory-made?
A: Yes. Openings are CNC-routed at the factory according to approved shop drawings, complete with internal structural reinforcement to maintain panel rigidity around apertures.
