Deligo 750ml Aerosol Grade Expanding Fire Rated B1 Foam

Deligo 750ml Aerosol Grade Expanding Fire Rated B1 Foam is a ready-to-use polyurethane foam that self-expands from a CFC-free propellant. Designed to seal gaps, joints and penetrations, it delivers robust insulation and fire performance without compromising movement. Cure time is fast—about 90 minutes for a 30mm bead—making it efficient for rapid filling and sealing. This SFF750 fire rated foam meets European standards (B1, difficult to ignite) and supports passive fire protection in electrical and building applications. Easy to apply, durable and versatile, it adheres to a range of substrates and expands to form a resilient, airtight barrier that helps limit heat and smoke transfer. A reliable choice for professional compatibility and safety.
