Our high-pressure expansion sealant (HPE) is a high-pressure exerting, graphite-based, intumescent sealant that expands when exposed to fire to protect penetrations, including pipes and cables. It also maintains the integrity and insulation performance of the seal.
The sealant is smoke, gas and airtight, mould-resistant and suitable for large service openings up to 300 x 100mm.
Under fire conditions, the product swells and exerts pressure on the surrounding substrates leading to the closure of the penetration. The integrity and insulation is then maintained by the stability of the remaining product char.
The HPE sealant is intended for use in all types of service penetration through walls and floors where fire integrity and insulation need to be preserved. It has excellent non-slump properties coupled with ease of application due to its water-based nature.
