Engineered for high-spec bio-facilities, microelectronics manufacturing suites, and hospital operating theatres requiring certified non-combustibility, moisture stability, and smooth antimicrobial cleanability.
Strategic cleanroom modular infrastructure aligning with France 2030, RE2020 environmental initiatives, and rigorous EU GMP Annex 1 requirements.
The Paris metropolitan area, widely recognized as the economic engine of France and a premier hub for European scientific research, is undergoing an unprecedented modernization of its high-tech infrastructure. From the internationally acclaimed Paris-Saclay innovation cluster (often dubbed Europe's Silicon Valley) to the specialized genomic corridors of Genopole in Évry and the oncological research zones around Villejuif Biopark, demand for advanced cleanroom partition systems has shifted toward next-generation inorganic materials. Among these, Magnesium Oxysulfate Panels (MOS / Magnesium Oxysulfide Panels) have emerged as the benchmark choice for mission-critical architectural envelopes.
Parisian biotech laboratories, cell & gene therapy centers, and sterile injectable production plants require surfaces capable of withstanding aggressive vaporized hydrogen peroxide (VHP) decontamination cycles without surface blistering or micro-fissuring.
High-precision microelectronics and quantum photonics research along the southern Île-de-France belt demand ISO Class 1 to ISO Class 5 clean environments with zero outgassing, high planarity, and antistatic powder-coated finishes.
Magnesium Oxysulfate chemistry provides European Class A1 / A2-s1,d0 non-combustibility and French M0 reaction-to-fire equivalence, directly fulfilling French ERP (Établissements Recevant du Public) and RE2020 low-carbon regulations.
Historically, standard Magnesium Oxychloride (MOC) panels faced severe operational challenges in humid environments, particularly the phenomenon of chloride ion release known as "sweating", which induces premature corrosion on galvanized steel studs, cleanroom aluminum extrusions, and concealed electrical conduits. Magnesium Oxysulfate (MOS) Panels eliminate this issue entirely by replacing magnesium chloride with high-purity magnesium sulfate solutions (MgSO₄·7H₂O). The resulting chemical matrix produces 5·1·7 phase crystalline structures [5Mg(OH)₂·MgSO₄·7H₂O], delivering superior anti-efflorescence performance, zero chloride leaching, enhanced water resistance, and an exceptionally flat composite surface ideal for pharmaceutical flush installations.

Customizable face sheet thicknesses (0.4mm - 0.8mm PPGI, stainless steel 304/316L, antistatic PVDF) and structural core combinations for European modular projects.
Essential guidance on Euroclass compliance, acoustic/thermal performance, and rapid modular installation in the Paris metropolitan territory.
MOS panels achieve European Reaction to Fire classifications A1 or A2-s1,d0 in accordance with NF EN 13501-1. Under high-heat conditions, the magnesium sulfate crystal matrix releases chemically bound water (endothermic dehydration), effectively suppressing flame spread and producing zero toxic smoke or flaming droplets, perfectly aligned with French M0 fire requirements.
We provide customized widths (typically 980mm or 1180mm standard, custom modular cuts), panel thickness from 50mm to 100mm, embedded PVC/aluminum conduits for wiring, pre-cut openings for HEPA Fan Filter Units (FFU), and interlocked flush cleanroom doors and double-glazed inspection windows.
From our Anji manufacturing facility, panels are packaged in export-grade protective filmed sea containers delivered via Le Havre or Antwerp direct to Île-de-France project sites, supported by comprehensive material test certificates, CE documentation, and BIM/AutoCAD installation schematics.
