FR Graphite by Protecta
Protecta FR Graphite is a water based fire classified sealing compound that contains a high concentration of heat expanding graphite material. This material is activated at 150°C and starts to intumesce (expand).
It can withstand fire and smoke for up to 4 hours.
This compound may be used in more extreme transits than FR Acrylic, for example cable trays to EI 180 and plastic pipes Ø110mm. Protecta 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. Protecta FR Graphite is designed to fire seal difficult services which traditional fire rated mastics do not achieve such as large plastic pipes.
It can be used with Protecta Mineral Fibre Bio to both reduce any shrinkage during curing and ensure correct width to depth ratio.
