PyroPro HPE Sealant 

A graphite based product which when exposed to fire, expands protecting penetrations including pipes and cables: maintaining the integrity and insulation performance of the seal.

PyroPro HPE is supplied in rigid cartridge format for application with an applicator gun; it has excellent non slump properties coupled with ease of application due to its water based nature.

The sealant is intended for use in service penetrations through walls and floors where fire integrity and insulation needs to be preserved. Under fire conditions the product swells 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.

The advantages of PyroPro HPE High Expansion Sealant are as follows:

• Sealing combustible and non combustible penetrations.

• Sealing of cables and telecommunication bunches. 

• Sealing combustible pipes up to 125mm (2 hours integrity and insulation).

• Suitable for use in irregular applications.

• Insulation properties.

• Easy clean up with water and odourless.

• Long life and paintable.

• Smoke, gas, water and air tight.

INSTALLATION

• Ensure the opening and any substrate which the product will come into contact with is clean, free  from dust and loose particles.

• Stonewool (min 80kg/m³) can be packed around the penetrations to aid depth of sealant.  Leave a minimum depth of 25mm (120 minutes)

• Apply PyroPro HPE to the remaining space around the penetrations.  The sealant should be installed at a ratio ⅛ of the diameter of the penetration, with maximum diameter being 125mm.

E.g. Penetration diameter = 90mm
Fill width = penetration diameter divided by ⅛
  = 90mm divided by ⅛
  = 12mm
See installation table below for further details.

• Once the sealant has been installed to the specified depth on both faces, smooth over the seal with a spatula and water. 

• All dimensions and tolerances should be in line with the recommended guidelines as dictated by the relevant test data   and assessments.
