🎯 Key Takeaways
-
🧊 Bulaopao panel is the core entity connecting surface materials, modified foam cores, and connection systems into a thermal insulation enclosure solution.
-
🔥 Fire rating: Bulaopao panels achieve Class B1 (modified foam) — better than standard foam (B2) but not Class A. Rock wool or magnesium cores are required for Class A applications.
-
🌡️ Thermal performance: Bulaopao panels achieve 0.022-0.030 W/(m·K) — comparable to polyurethane and better than rock wool or magnesium.
-
📏 Thickness selection ranges from 50-75mm for chilled storage/food processing to 150-200mm for ultra-low temperature applications.
-
💧 Moisture resistance: closed-cell modified foam structure offers excellent moisture resistance, superior to rock wool.
-
🏭 SAMZOON operates as a Foshan-based source manufacturer, bridging product supply with technical guidance for food processing and cold storage projects across South China.
