DIN 4102 B2 Fire Retardant Expanding Foam - 55L Yield, 0.034 W/(m·K) Thermal Conductivity

This DIN 4102 B2-certified polyurethane foam provides superior fire-retardant performance with self-extinguishing properties that stop combustion immediately when the fire source is removed. The moisture-curing formula delivers durable sealing, thermal insulation, and soundproofing capabilities for various construction applications.

• B2 Fire Rating (DIN 4102-1) - Enhanced flame resistance for critical safety applications
• Self-Extinguishing - Stops burning immediately when flame source is removed
• Closed-Cell Structure - Water-resistant, rigid, and dimensionally stable
• High Expansion Rate - Fills gaps and voids completely for airtight sealing
• Thermal & Acoustic Insulation - Reduces heat transfer and dampens sound effectively
• Strong Adhesion - Bonds securely to most construction materials
• Non-Shrinking - Maintains long-term stability without cracking or settling
• Easy Application - Cures with ambient moisture for quick installation

• Fire-rated door and window installations
• Sealing joints in walls, floors, and ceilings to block fire and smoke
• Penetration sealing for pipes, ducts, and electrical conduits
• Roof and facade gap filling for weather and fire resistance
• Insulation in cold storage or industrial environments requiring fireproofing
