Astroflame HPE Sealant is an acrylic based graphite sealant used to reinstate the fire resistance performance of wall and floor constructions where they have been provided for the penetration of single or multiple services, to form penetration seals where gaps are present.

Astroflame HPE Sealant expands upon contact with heat, also known as intumescent or reactive material. The sealant is gunned or trowelled into the annular space in or between the separating element/elements to a specific depth utilising backing materials.

Features & Benefits

The intended use of Astro 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 Astro HPE Sealant may be used to provide a penetration seal in, are as follows:

• Suitable for use in rigid wall and floors, flexible wall and batts in wall and floor
• Linear Joints up to 20mm wide
• Large service openings up to 300 x 100mm
• Batt aperture up to 1100mm x 750mm
• Metallic Pipes, Cables, Cable Bunches (inc Telecommunication), Cable Trays and Cable Ladders
• Combustible Pipes up to 125mm dia - PVC, PE, PP, ABS and PEX.
• Use with sealing elastromeric foam and glass wool insulation
• Suitable for use in irregular applications
• Causes no known effects to plastic pipes, plastic cables, sheathing or metallic components
• Contributes to Green Building
• Easy clean up with water and is odourless
• Long life and paintable
• Smoke, gas, water tight and air tight
• High Expansion Ratio
• Resists fungi and vermin

Technical Data

Installation

Backing Material

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

Installation

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

All service's 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 Astro HPE Sealant 20mm annular and 25mm deep around all services effectively, make sure that you fill all of the annulus and to compact the Astro HPE Sealant into the annular gap.

Once compacted smooth off the Astro HPE Sealant to produce a nice professional looking finish.

Please refer to the Technical Data Sheet (also available from the Data Sheets tab further above) for more data on the following installations:

Uponor Application - Uponor Valve System

The drywall construction was of overall dimensions 3000mm wide by 3000mm high by 100mm thick. The framing comprised 50mm wide galvanised mild steel studs, at maximum 600mm centres, friction fitted into galvanised steel head and base channels.

Each side of the stud frame was faced with two layers of 12.5mm thick ‘Gypsum’ Type F plasterboard. The framework was infilled with 50mm thick mineral wool insulation having a nominal density of 100kg/m³.

The wall was provided with eight circular apertures, which was penetrated by a range of shower units.
