🎯 Key Takeaways
-
🔥 Magnesium sandwich panels achieve Class A non-combustible fire rating (GB 8624), making them suitable for cleanrooms, GMP workshops, operating rooms, and other strict fire acceptance applications.
-
💧 Moisture resistance is a key strength of magnesium panels — the dense core resists moisture absorption better than untreated rock wool.
-
⚠️ Halogen return (返卤) is a known risk in low-quality magnesium oxychloride panels — controlled raw material ratios, proper curing, and sealing are essential.
-
🔄 Magnesium oxysulfate panels offer an alternative for high-humidity applications, reducing halogen return risk compared to oxychloride cores.
-
🧊 Magnesium vs. rock wool: magnesium offers better moisture resistance, lighter weight, easier machinability, and generally lower cost; rock wool offers higher density and acoustic performance.
-
🏭 SAMZOON operates as a Foshan-based source manufacturer, bridging product supply with technical guidance for cleanroom engineering firms and medical project owners across South China.
