Fire-retardant foaming sealant
Protecta® FR Graphite is a water-based foaming sealant with fire certification, which contains a high concentration of thermally expanding graphite material.
The sealant foams when exposed to fire and closes openings around the penetrations during the combustion of some flammable or low melting point materials. This mixture can be used in more demanding passages than FR Acrylic, for example in cable trays up to EI 180 and plastic pipes Ø 110 mm.
