Description

Fire Rated & Acoustic Expanding PU Foam is a modified one component polyurethane foam for the filling/sealing of joints and gaps requiring fire retardant properties. The foam expands rapidly after dispensing and quickly cures to a fine honeycomb structured foam by reacting with atmospheric moisture.

The products comply with DIN4102, Part 1, Class B1 and have been tested to BS 476 Part 20, and BS EN ISO 140-3:1995.

Suitable for general gap filling, bonding and insulation applications where a fire retardant 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 where a recognised level of fire protection and/or acoustic performance is required. 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 and is supplied in pressurised aerosol canisters in both Gun and Nozzle grades.
