FireMastic-HPE intumescent mastic sealant is the best-in-class with the highest expansion rate and superior charring for closing pipes and multiple service bundles.

Fire conditions causes FireMastic-HPE to expand >40 times its volume and forms a solid char. This maintains insulation in even the largest penetrations.

In a fire situation, FireMastic-HPE expands with enough pressure to close combustible pipes and seal around cables and metal pipes, maintaining the integrity and insulation of the seal and resisting the passage of fire and smoke, yet without placing any unnecessary pressure on the substrate.
