Fire rated expanded foam can be used as an efficient seal against smoke and gas, providing up to 240 minutes fire rating. As well as being useful due to its excellent filling characteristics, fire rated foam has high thermal properties and provides acoustic insulation.
FF197 Gun Grade Fire Rated PU Foam with a fire rating of 240 minutes
FF197 is a modified, single component, fire rated polyurethane foam.
FF197 is used to seal linear gaps throughout the fire rated areas of a building.
It is perfect for sealing gaps found around fire rated doors, and can be easily applied with a straw nozzle or professional foam gun.
FF197 has excellent adhesion to most building materials such as wood, brick, stone, cement, plaster, polystyrene, cable sheaths, metals, plastics and firmly sets in approximately one hour.
Benefits of FF197 Gun Grade Fire Rated PU Foam
• Certified to the latest British and European standards
• Cures to form a semi-rigid foam that is able to accommodate some degree of movement of the joint
• Acts as an effective fire seal for up to 4 hours when used with FS701 intumescent acrylic or FS703 silicone sealant
• When used in a linear seal for gaps up to 20 mm wide between timber door frames and supporting walls, it can provide 30 and 60 minutes fire resistance
• Bulk filling of irregular gaps and voids.
• Outstanding fire resistance even without capping
• Quick and easy installation
• Excellent adhesion to most substrates
• Good smoke sealing, acoustic and insulation properties.
• Service temperature: -40 to +90°C.
Limitations of FF197 Gun Grade Fire Rated PU Foam
As with all PU foams, FF197 will not adhere to Teflon, polyethylene or silicone coated surfaces. The cured foam is adversely affected by UV light and should be covered with a suitable sealant such as FS703 silicone or FS701 intumescent acrylic.
