FSi PyroPro HPE Intumescent Graphite Sealant is a water based acrylic sealant used to reinstate the fire resistance of wall and floor constructions in apertures when penetrated by multiple services. PyroPro HPE Sealant has been developed utilizing specialist intumescent technologies which result in the sealant expanding in the presence of heat or fire.

This expansion is fast acting and up to 25 times. The expanding sealant fills the void left by combusting materials and remains in place, exerting a pressure on the surrounding substation upholding the fire resistance of the compartment. This uniquely formulated product allows it to be tested and Certified to internationally recognised standards, including, Certifire, CE marking and UL Listings.

PyroPro HPE Sealant has been tested and Certified as part the FSi Fire Stopping range.

Intended Use

The intended use of Pyropro HPE Sealant is to reinstate the fire resistance performance of rigid and flexible wall and floor constructions where they are penetrated by various cables, plastic and insulated metallic pipes.

The specific elements of construction that the system Pyropro HPE Sealant may be used to provide a penetration seal in, are as follows:

• Rigid walls and floors, flexible wall and batts in walls and floors
• Linear Joints up to 20mm wide
• Large service openings up to 300mm x 100mm
• Batt aperture up to 1100mm x 750mm
• Metallic Pipes, Cables, Cable Bunches (inc Telecommunication), Cable Trays and Cable Ladders

Technical Data

Backing Material

Mineral wool (min. 80kg/m³) or PE backing rod where required can be used as backing material for Pyropro HPE Sealant. Backing material is not needed within all installations, though the Pyropro HPE Sealant should be installed correctly to achieve the performance needed.

Key Installation Points

Ensure that the aperture and services in question are tested with Pyropro HPE Sealant, and the site conditions are within the application specification. An annular space needs to be present around the service to allow sufficient installation depth.

All services and apertures need to be clean and clear of all dust and loose particles. The aperture temperature needs to at 5℃ or above at time of installation.

Upon installation make sure that you install the Pyropro HPE Sealant 20mm annular and 25mm deep around all services effectively, ensure that you fill all of the annulus and compact the Pyropro HPE Sealant into the annular gap.

Once compacted, smooth off the Pyropro HPE Sealant to produce a professional finish.
