3x Soudal Trade Expanding Foam B1 Fire Class 750ml Hand Held Foam Filler+Gloves

3x Soudal Trade B1 Fire Rated Expanding Foam 750ml Hand Held PU Gap Filler AerosolSoudal Trade Expanding Foam B1 is a one-component, moisture-curing, self-expanding polyurethane foam supplied ready to use in a 750ml aerosol can.Designed for professional filling, sealing and insulation applications, the foam offers high filling capacity, excellent stability, strong bonding properties and good adhesion to most surfaces, except PE, PP and PTFE.The product is classified B1 according to DIN 4102-1, making it suitable for applications where this building material fire reaction classification is required. It also provides effective thermal and acoustic insulation, with a thermal conductivity of 0.035 W/m.K and sound insulation of 58 dB.A 750ml can provides approximately 32 litres box yield or approximately 22 metres joint yield under the specified test methods. The foam has a skin formation time of approximately 8.5 minutes and a cutting time of approximately 65 minutes.Typical applications include filling and insulating mechanically fixed window and door frames, filling cavities, sealing openings in roof constructions, improving thermal insulation in cooling systems and creating acoustic baffles.Key Features & BenefitsB1 Fire Reaction Class according to DIN 4102-1One-component polyurethane foamMoisture-curing formulaSelf-expanding and ready to use750ml aerosolExcellent stabilityHigh filling capacityNo post-expansion after curingShrinkage after curing <5%Approx. 135% expansion during curingGood adhesion to most surfacesVery good bonding propertiesHigh thermal and acoustic insulation58 dB sound insulation0.035 W/m.K thermal conductivityApprox. 32L box yield per 750mlApprox. 22m joint yield per 750ml8.5-minute skin formation65-minute cutting timeTemperature resistant from -40°C to +90°C
