AMRO B1 Fire Retardant PU Foam 750ml
The AMRO B1 Fire-Retardant PU Foam 750ml is a self-extinguishing Class B1 polyurethane foam, designed for fire-resistant sealing and insulation in critical applications. This moisture-cured, aerosol-dispensed foam draws humidity from the air for curing, offering an economical, convenient, and effective method for installing Fire Code compliant structures. AMRO B1 Fire-Retardant PU Foam seals concealed penetrations, preventing the spread of fire by creating a fire block from floor to floor or room to room. It forms an airtight, water-resistant bond with joints, wood, drywall, metal, masonry, glass, and most plastics, making it ideal for electronics enclosures, fire-rated construction, and DIY projects. Free of CFC gases, this foam ensures environmentally friendly application.
