 |
Description |
Webbflex B1 Fire Resistant Expanding PU Foam is a modified one component polyurethane foam for the filling / sealing of joints and gaps requiring fire resistant properties. The foam expands rapidly after dispensing and quickly cures to a fine honeycomb structured foam by reacting with atmospheric moisture. The cured product meets Class DIN4102, Part 1, Class B1 and can provide over 2 hours fire resistance in linear joints when tested to BS 476 Part 20. It has excellent thermal and acoustic insulation properties and forms a strong bond to most construction materials. The propellant used has no ozone depleting potential. The product is supplied in pressurised aerosol canisters in both Gun and Nozzle grades. |
|
Applications |
Webbflex B1 Fire Resistant PU Foam is suitable for general gap filling, bonding and insulation applications where a fire resistant fill is required. These include the perimeter sealing and fixing of fire resistant windows and doors and the sealing of mechanical and electrical service penetrations through compartment walls and floors. |
