Description
Astro high pressure expansion (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.
The sealant expands upon contact with heat, also known as intumescent or reactive material, Astro HPE Sealant is supplied within 310 ml cartridges and 600 ml foils. The sealant is gunned or trowelled into the annular space in or between the separating element/ elements to a specific depth utilising backing materials.
*For specific details please refer to the test certification.
Features and benefits:
- CE & UKCA marked.
- ULEU accreditation.
- Large service openings up to 300 x 100 mm.
- Tested in accordance with EN 1366-3: 2009.
- Combustible pipes up to 125 mm diameter - polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene styrene (ABS) and cross-linked polyethylene (PEX), please refer to the test certification.
- Causes no known effects to plastic pipes, plastic cables, sheathing or metallic components.
- Easy clean up with water and is odourless.
- Smoke, gas and air tight.
- High expansion ratio.
- Mould resistant.
