RAWLPLUG RPP-B1 Fire-Resistant Gun-Applied Polyurethane Foam 750ml

The RAWLPLUG RPP-B1 is a professional-grade, fire-resistant polyurethane foam specifically engineered for gun application. This 750ml canister is designed to provide reliable sealing for joints, gaps, and voids in building structures where fire safety is a critical requirement. By expanding to fill irregular spaces, it creates a robust barrier that maintains its integrity under demanding conditions, offering both thermal and acoustic insulation properties essential for modern construction and renovation projects.

Advantages

This fire-resistant foam stands out due to its high yield, producing up to 45 liters of cured material from a single canister, which optimizes material usage on site. Its professional gun-applied formulation ensures precise application, reducing waste and allowing for better control in tight or difficult-to-reach areas. The product is formulated to meet stringent fire safety standards, providing peace of mind in residential and commercial applications. Furthermore, its excellent adhesion to common construction materials like concrete, brick, plaster, and wood makes it a versatile solution for various sealing tasks.

Suitable for

• Sealing gaps around door and window frames requiring fire resistance
• Filling penetrations for pipes and cables in fire-rated walls
• Insulating joints between partition walls and ceilings
• General construction sealing where certified fire protection is mandatory

This product may not be suitable for applications involving constant exposure to direct UV radiation, as the foam should be protected with a suitable sealant or coating. It is also not intended for structural load-bearing purposes or for use in areas where the foam will be permanently submerged in water.

Key specifications

• Volume: 750ml
• Yield: Up to 45 liters
• Application method: Gun-applied
• Fire resistance: Certified for fire-rated applications
• Insulation properties: Thermal and acoustic

To use the RAWLPLUG RPP-B1, ensure the surfaces are clean, dust-free, and slightly moistened to improve adhesion and curing. Shake the canister vigorously for at least 30 seconds before attaching it to a professional foam gun. Apply the foam by filling the gap to approximately 50-60% of its depth, as the material will expand during the curing process. Once fully cured, any excess foam can be trimmed with a knife and covered with a suitable finish.

What to consider before purchase

• Verify the fire safety requirements of your specific project
• Ensure you have a compatible professional foam gun for application
• Calculate the required volume based on the 45-liter yield per canister
• Check compatibility with the substrate materials

For optimal results, store the canister in an upright position at room temperature and use the product within the recommended shelf life. Always wear appropriate protective equipment, including gloves and safety glasses, during application.
