Cleanroom Material Selection Guide: Key Criteria for Contamination Control

🔍 1. Core Performance Requirements

✔️ Low Contamination

• Use smooth, non-porous surfaces (stainless steel, PVC, aluminum) to minimize dust accumulation.

• Avoid porous/fibrous materials that trap particles.

✔️ Corrosion Resistance & Cleanability

• Prioritize chemical-resistant materials (e.g., stainless steel, epoxy resin floors).

• Install seamless flooring (self-leveling epoxy, PVC) with ≥30mm radius coving at wall junctions.

✔️ Functional Adaptability

• ESD-Sensitive Zones: Antistatic materials (conductive PVC flooring, aluminum honeycomb panels).

• High-Temperature Areas: Heat-resistant boards (glass magnesium, rockwool core).

• Humid/Corrosive Environments: Acid-proof materials (sulfur-oxygen magnesium cement core).

• 

🧩 2. Material Selection by Category

⚡ 3. Scenario-Specific Solutions

• Medical/Bio Labs: Antibacterial panels (stainless steel + glass magnesium), Class A fire rating.

• Electronics Cleanrooms: ESD-safe materials (color-coated steel + aluminum honeycomb core) to prevent static dust adhesion.

• Food/Chemical Plants: Corrosion-resistant cladding (stainless steel + sulfur-oxygen magnesium core).
• 
  

🛠️ 4. Construction & Compliance

✓ Structural Design

• • Seal joints/window gaps with specialized sealants for airtightness.

  • Use independent supports for ceilings/walls (no shared equipment brackets).

✓ Safety Compliance

• • Meet fire ratings (Class A rockwool) & ESD standards.

  • Adhere to GMP/FDA regulations with eco-friendly materials (E1 emission class).

✓ Cost Efficiency

• • Sulfur-oxygen magnesium panels for standard cleanrooms; stainless steel for Class 100/1000 zones.

  • Modular panels reduce retrofit costs.

💎 Summary: Base selection on cleanliness class, operational context, and safety norms. Prioritize surface smoothness, chemical resistance, and hermetic sealing. Ensure construction eliminates dead corners.
