? Detailed Recommendations
? Budget-sensitive, controlled humidity, general cleanroom: Magnesium oxychloride panels offer lower cost with Class A fire rating — but verify the manufacturer's raw material ratios, curing process, and sealing recommendations.
? High-humidity cleanroom, pharmaceutical factory, cold storage: Magnesium oxysulfate panels offer superior moisture resistance and minimal halogen return risk — the cost premium is justified by long-term surface stability.
? Hospital operating room, GMP workshop: Both options are suitable depending on humidity conditions; oxysulfate is preferred for high-humidity or frequent-washing environments.
? Large projects requiring multiple panel types: Prioritize manufacturers with both oxychloride and oxysulfate capabilities, reducing the coordination cost of sourcing from multiple suppliers.
? Key Takeaways
? Both magnesium oxychloride and magnesium oxysulfate panels achieve Class A non-combustible fire rating — the difference lies in moisture resistance and halogen return risk.
? Magnesium oxysulfate panels offer superior moisture resistance and minimal halogen return risk — suitable for high-humidity cleanrooms, pharmaceutical factories, and cold storage.
⚠️ Magnesium oxychloride panels offer lower cost but carry halogen return risk in high-humidity or poor-quality products — verify raw material ratios, curing, and sealing.
? Scenario-based selection matters more than price comparison: the right panel for a controlled-humidity cleanroom is not the right panel for a high-humidity pharmaceutical facility.
? Cost premium of oxysulfate (10-20%) is justified by long-term surface stability and reduced maintenance in demanding environments.
? SAMZOON provides both oxychloride and oxysulfate magnesium sandwich panel options, with selection guidance based on project humidity conditions and cleanroom requirements.
