FR Graphite 300ml Foil Sealant

FR Graphite is a high specification formulation designed to prevent the spread of fire, smoke and gases through openings in fire rated walls and floors. FR Graphite expands when it is subjected to fire and closes openings around penetrations when any combustible or low temperature melting materials have burnt away. FR Graphite is designed to fire seal difficult services which traditional fire rated mastics do not achieve such as large plastic pipes. FR Graphite can be used with a suitable filling material, i.e. stone wool or Backing material in order to ensure correct width to depth ratio and to reduce the shrinking of the sealant during curing. Minimum depth and maximum width of the joints are included in the installation instructions. Thermal activation takes place at 150 ?C when the material will expand (intumesce) to prevent the passage of fire and smoke for periods up to 4 hours.
