Firemastic HPE Intumescent Sealant

Boss Passive Fire

Boss FireMastic HPE

FireMastic-HPE™ is a high pressure exerting fire sealant to surpass all other sealants. Our flagship sealant is tested and approved to change the way firestopping is applied to pipes and penetrations.

Approved to AS1530.4 and EN1366 and offers an FRL of up to -/120/120 in a wide range of penetration systems, outperforming other leading sealants in independent fire tests.

FireMastic-HPE is a graphite-based, thixotropic, one-part acrylic emulsion that is designed to resist the passage of fire and smoke. Under heat, FireMastic-HPE will expand with enough pressure to close PVC pipes and seal around cables and metal pipes to maintain the integrity and insulation performance of the seal, yet without placing any unnecessary pressure on the building substrate.

FireMastic-HPE is supplied in cartridges suitable for caulking via an applicator gun or also available in buckets. It has excellent non-slump properties coupled with the ease of application due to its water-based nature.

The sealant is intended for use in either linear gap seals or services penetrations through walls where fire integrity and insulation needs to be preserved. Under fire conditions the product expands up to 40 times its volume and exerts pressure to the surrounding substrates leading to closure of the penetration. The integrity and insulation is then maintained by the stability of the remaining product char.
