Soudal 128450 B2 Gun Grade Fire Expanding Foam 750ml (Pack of 12 ) 128450-12

Soudal 128450 B2 Gun Grade Fire Expanding Foam 750ml (Pack of 12 )Description:Soudal 128450 B2 Gun Grade Fire Expanding Foam is a professional-grade, one-component, polyurethane foam filler with fire-retardant properties. Designed for use with foam applicator guns, this moisture-curing foam provides rapid expansion, excellent adhesion, and superior thermal and acoustic insulation. Classified B2 under DIN 4102, it offers up to 2 hours of fire resistance depending on joint configuration (EN 1366-4). Ideal for passive fire protection and general construction applications, including sealing joints, pipe penetrations, and window or door frame installations.Features:Fire-rated expanding foam (B2 classification)Up to 2-hour fire resistance (EN 1366-4)High yield per can and boxExcellent thermal and acoustic insulationSuitable for use in passive fire protection systemsFast skinning and curing timesHigh adhesion to most construction surfaces (excluding PE, PP, PTFE)No significant shrinkage or post-expansionFor gun application only - not hand heldNot UV-resistant - must be covered once curedSpecifications:Base: PolyurethaneConsistency: Stable, thixotropic foamCuring system: Moisture curingSkin formation: Approx. 8 minutes (EN 17333-3)Cutting time: Approx. 30 minutes (EN 17333-3)Thermal conductivity: 0.035 W/m·K (EN 17333-5)Sound insulation: 60 dB (EN ISO 717-1)Density: Approx. 24 kg/m³ (EN 17333-1)Fire classification: B2 (DIN 4102-1)Fire resistance: Up to 2 hours (EN 1366-4, depending on joint configuration)Expansion during curing: Approx. 73%Expansion after curing: <1%Shrinkage after curing: <5%Compression strength: Approx. 40 kPa (EN 17333-4)Shear strength: Approx. 66 kPa (EN 17333-4)Tensile strength: Approx. 105 kPa (EN 17333-4)Elongation at Fmax: Approx. 20%Closed cell content: Approx. 62% (ISO 4590)Water absorption: Approx. 0.28 kg/m² (ISO 29767)Yield per can: Approx. 30 metres of foamYield per box: Approx. 45 litres of foamTemperature resistance: -40°C to +90°CShelf life: 12 months (upright, unopened, +5°C to +25°C)Colour: Champagne
