Clean room sandwich panel (also named purification panel) is a dedicated modular composite enclosure material engineered exclusively for controlled cleanroom environments. It consists of double-sided hygienic metal facer sheets thermally bonded to lightweight insulating core material via high-strength PU adhesive, forming a seamless, dust-proof, easy-to-disinfect wall and ceiling system.
1. Outer Facer Sheet Material Options
- Pre-painted galvanized steel (Standard Grade)
Thickness: 0.3–0.6mm; matte white RAL9003 cleanroom coating, anti-fingerprint, antibacterial treatment (ISO 22196 ≥99.9% antibacterial rate). Cost-effective for electronics, cosmetic and medium-grade ISO7/8 clean zones.
- SUS304 / SUS316L Stainless Steel (Premium Medical/Pharma Grade)
Wire drawing anti-corrosion surface, withstands long-term wiping with alcohol, hydrogen peroxide and chlorine disinfectants. Mandatory for operating rooms, vaccine workshops, food sterile filling and high-corrosion labs.
- Anti-static ESD coated steel (Electronics Special)
Surface resistance 10⁶~10⁹Ω, eliminates static discharge damage to chips, semiconductors and optical components.
- Optional: Aluminum alloy sheet for lightweight clean booth frames.
2. Main Core Material Types & Performance Comparison
(1) Rock Wool Sandwich Panel (Class A1 Non-combustible, GMP Fire Standard)
- Core: Basalt inorganic rock wool, density 80–120kg/m³, A-class fireproof, 1–3 hour fire resistance limit
- Advantages: Non-flammable, sound insulation, inorganic anti-mold, high structural rigidity
- Best for: Pharmaceutical aseptic workshops, hospital operating rooms, chemical labs, high fire-risk clean zones
- Limitation: Slightly heavy, requires full sealing for high-humidity environments
(2) PU / PIR Polyurethane Panel (Ultra Energy-Saving Insulation)
- Core: Closed-cell rigid PU foam, thermal conductivity λ=0.022~0.026 W/m·K (industry top insulation performance)
- Fire grade: B1 low flame spread; excellent moisture & water resistance
- Best for: Cold storage cleanrooms, temperature-sensitive biotech labs, constant humidity production lines
- Advantages: Lightweight, ultra-low HVAC power consumption, long service life
(3) EPS Flame-Retardant Panel (Economical Medium Cleanroom)
- Core: Closed-cell FR-EPS foam, B2 flame retardant, ultra-lightweight, low unit cost
- Best for: Electronics assembly, cosmetic packaging, temporary modular clean booths (ISO7/8 low fire risk areas)
- Limitation: Not recommended for ISO5 Class100 sterile pharmaceutical zones or open-flame workshops
(4) Aluminum Honeycomb Panel (Ultra-Light High Strength Premium)
- Core: Aviation-grade aluminum honeycomb grid, hollow lightweight structure, high flatness
- Advantages: Zero particle shedding, no moisture absorption, lightest weight for long-span ceiling
- Best for: Semiconductor Class100 ultra-clean zones, precision optical labs, high-end modular hard wall clean booths
(5) Magnesium Oxide Glass Magnesium Panel
- A-class fireproof, moisture-proof, anti-mold, suitab
