TECHNICAL DATA SHEET AF GRAPHIT FOAM Two-component fire-resistant polyurethane foam DESCRIPTION AF GRAPHIT FOAM is a two-component polyurethane foam with graphite added and certified under EN 1366-3 for EI 180 protection of mechanical and electrical system penetrations in walls and floors. Using graphite, the foam expands during application and heat during a fire. This property makes the product versatile and suitable for combustible material penetrations, which would be destroyed during a fire. The special cartridge, with the help of a spray gun, allows the simultaneous extrusion of the two components and their mixing inside the application nozzle. AF GRAPHIT FOAM is a simple and flexible solution, ideal for openings with several pass-through close elements. DIRECT APPLICATION Electrical cables and corrugated pipes in a cable tray Combustible pipes Multilayer pipes including bundles Insulated and uninsulated metal pipes Mixed penetrations FEATURES Cartridge capacity: Colour: Reaction time: Drying time: Ready to cut: Increase in volume at 20 °C Yield: Storage temperature: Application temperature: 330ml dark brown about 10 sec about 30 sec Approx. 1 min 3-5 times (free expansion) 1000-1700ml approx. 5-35 °C 10-35 °C PACKAGING AND STORAGE Pack of 1 x 330ml cartridge equipped with a dispenser/mixer Under normal conditions (5-35°C) the product remains intact for 12 months APPLICATION METHOD 1. 2. 3. 4. 5. screw the mixer onto the cartridge and insert the cartridge into the spray gun; apply AF GRAPHIT FOAM starting from the furthest point, without immersing the mixing nozzle in the extruded product; fill the opening, reaching a minimum depth of 120 mm; avoid interrupting extrusion for more than five seconds to prevent sudden hardening of the material in the mixer; when hardened, remove the overowing edges with a cutter. Spray gun We recommend using the manual gun to apply the necessary force during the extrusion process. Using manual applied force the spray gun provides a quick and easy release of the mixed bicomponent product. SPECIFICATION Supply and application of intumescent semi-rigid foam AF GRAPHIT FOAM, made of two-component intumescent polyurethane polymer with free expansion of 3-5 times its original volume, contained in a 330 ml two-wire cartridge. The system is certified for EI 120/180 protection of wall and floor system penetrations.
