Blend Polyol for Building Sandwich Panel B1 Class Fire Retardant
This flame retardant polymeric MDI two-component rigid polyurethane foam system is engineered to meet stringent building insulation fire safety standards while delivering superior thermal insulation performance. Featuring a B1 fire rating per DIN 4102 and Class B classification under EN 13501-1, this halogen-free formulation uses a phosphorus-nitrogen synergistic flame retardant system that achieves self-extinguishing behavior with minimal smoke generation and zero halogen acid gas emissions during combustion.
The system is purpose-built for continuous lamination sandwich panel production, spray-applied insulation, pour-in-place applications, and discontinuous panel manufacturing for cold storage warehouses, refrigerated transport vehicles, LNG pipe insulation systems, and commercial building envelope solutions where both thermal efficiency and fire safety compliance are non-negotiable requirements.
Key Features
B1 Fire Rating with Halogen-Free Technology: Certified B1 per DIN 4102-1 and Class B-s2,d0 per EN 13501-1 using phosphorus-nitrogen intumescent flame retardants. Zero brominated or chlorinated compounds ensure no corrosive or toxic halogen gas release during fire events.
Exceptional Thermal Insulation Performance: Achieves thermal conductivity as low as 0.020 W/(m*K) at optimal density, significantly reducing building energy consumption. Over 92% closed cell content minimizes thermal bridging and serves as an effective air and moisture barrier.
Versatile Blowing Agent Compatibility: Available with HCFC-141B, cyclopentane for zero ODP applications, or next-generation HFO blowing agents for ultra-low GWP compliance.
Optimized Reaction Profile for Continuous Processing: Adjustable cream time from 15 to 35 seconds, gel time from 60 to 120 seconds, and tack-free time from 90 to 180 seconds tuned for production line speeds up to 15 meters per minute.
Excellent Dimensional Stability: Dimensional change limited to less than 1.5% after 24-hour conditioning at both minus 30°C and plus 80°C, ensuring panel flatness and structural integrity.
Low Smoke Density for Occupant Safety: Smoke Density Rating below 75 per ISO 5659-2, significantly lower than conventional halogenated flame retardant systems, providing critical visibility time for safe evacuation.
High Compressive Strength for Structural Panels: Compressive strength exceeding 200 kPa at 40 kg/m³ core density ensures structural rigidity under wind load, snow load, and handling stresses.
This flame retardant rigid PU foam system is the preferred insulation solution across a wide spectrum of temperature-controlled and fire safety-critical construction applications. Primary applications include continuous and discontinuous metal-faced sandwich panels for cold storage warehouses, food processing facilities, and pharmaceutical clean rooms; spray-applied thermal insulation for building envelopes, roof decks, and underground parking ceilings; LNG and cryogenic pipe insulation systems; prefabricated modular housing and containerized building units; refrigerated truck and trailer body panels; and industrial tank and vessel insulation for petrochemical processing facilities.
Packaging & Quality Assurance
Component A (Polymeric MDI Isocyanate) is supplied in nitrogen-blanketed 250kg net steel drums or 1,250kg IBC totes. Component B (Formulated Blend Polyol) is packaged in 250kg steel drums or 1,000kg IBC totes. All packaging meets UN dangerous goods transportation requirements. Each production batch undergoes comprehensive quality control protocol including foam reactivity profiling, core density verification, thermal conductivity measurement, compressive strength testing, fire performance validation, and dimensional stability evaluation. A detailed Certificate of Analysis, Safety Data Sheet, and comprehensive processing guideline document accompany every shipment.
