Description

Astroflame Intumescent PFP FR Acrylic Sealant, designed to prevent the spread of fire and smoke through joints and openings in fire rated walls and floors (including openings formed around building service penetrations); the Astro PFP FR Acrylic will also maintain the acoustic design performance.

When subjected to atmospheric conditions, the sealant cures however, it will retain a degree of elasticity for joint movement. Under fire exposure, The Astro PFP FR Acrylic creates a robust fire seal by the formation of a durable intumescent char.

The Astro PFP FR Acrylic can be used with a suitable filling material i.e. stone wool or Astro PFP FR backing material in order to secure correct width to depth ratio, and to reduce the shrinking of the sealant during curing. Minimum depth and maximum width of the joints are included in the installation instructions. Thermal activation takes place at approx. 180°C when the material will expand (intumesce) and prevent the passage of fire and smoke for periods up to and beyond 4 hours.

PFP FR Acrylic complies with the requirements of GEV, and the results correspond to the EMICODE emission class EC 1 PLUS - the best possible environmental and indoor hygiene health protection mark*). Tested by Eurofins Product Testing, report number G12870B. *) Excludes the pure white version.



Analysis of cPVC Pipes e.g. BlazeMaster


Analysed using Fourier Transform Infrared (FTIR) Spectroscopy; examination of the sealant contact regions of the cPVC pipe after removal of the sealant showed no evidence of visible discolouration or changes at the pipe surface.

PFP FR Acrylic has also been tested for chemical resistance of a sealant when applied to a cPVC pipe. The sealant does not affect cPVC pipes as the tests showed no difference between the control and exposed results at Yield.

Tested by Intertek, report numbers IWTN/W000009628ARL001 and WTN/W000009628RLM001.

Pipe End Configurations


When testing pipes, one can choose not to cap (or close) the pipe, or cap the pipe inside the furnace, or outside the furnace, or on both sides. The configuration chosen depends on the intended application of the pipe and/or the installation environment.

The code defining if a pipe is capped is stated after the fire classification. For instance, EI 60 C/U which means the pipe was capped inside the furnace, and uncapped outside the furnace. The test configuration defines the approvals possible.

Our engineering judgment based on EN 1366-3:2009 are:

Intended use of pipe Pipe end condition4
Rainwater pipe, plastic At drainage U/U1
Not at drainage C/C2
Drainage or sewage pipe, plastic Ventilated drain U/U1
Unventilated drain U/C1
Drain w/water trap U/C1
Not at drainage C/C2
Pipe in closed circuit (water, gas, air, electricity etc.) C/C2 3
Flue gas recovery system pipe, plastic U/C1
Pipe with open ends and ≥ 50cm length on both sides, plastic U/U2
Pipe supported by suspension system, metal Fire rated support C/U1
Non-fire rated U/C1
Waste disposal shaft pipe, metal U/C1

  1. Suggested in EN 1366-3:2009.
  2. Astroflame’s judgment based on tests.
  3. Metal pipes should have fire rated support.
  4. U/U classified fire seals cover C/U, U/C and C/C. C/U classified fire seals cover U/C and C/C. U/C classified fire seals cover C/C.

Installation


  1. Before installing Astro PFP FR Acrylic ensure that the surface of all service penetrations and surrounding construction is free from all loose contaminants, dust and grease.
  2. Where Astro PFP FR Acrylic is to be installed against surfaces that cannot tolerate direct contact; appropriate surface preparation should be made (contact Astroflame for guidance in these cases). For paints sensitive to sealing compounds, priming with a PVA primer is recommended.
  3. As Astro PFP FR Acrylic is water based, in cases where corrosion protection is a problem; some metals may require a barrier between the sealant and the metal surface prior to this installation.
  4. When installing the sealant in gypsum boards, the exposed edges of the board can be wetted with water, or Astro PFP FR Acrylic diluted with water to prime the surfaces helping adhesion and preventing excessive joint shrinkage.
  5. When installing Astro PFP FR Acrylic in hollow floor slabs or boards, fire seals specified as single sided should be installed from the soffit side of the floor assuming there is sufficient thickness of concrete below the void to follow the installation guide. Where this is not the case, tubular voids should be filled with stone wool normally the same thickness as the depth of the floor slab. Alternatively, simply fire seal on both sides.
  6. When installing any backing material, cut this slightly oversize and insert into the gap ensuring a tight friction fit. Ensure correct depth is achieved.
  7. Fill the gap or joint with Astro PFP FR Acrylic to the required depth. Refer to the drawings on following pages 2 to 21 for guidance on joint design/dimensions. If installation does not have to meet any specific fire specification, it is recommended that a width to depth ratio of 2:1 is utilized, with a minimum depth of 12mm of sealant.
  8. Apply the sealant generously to prevent air bubbles. Finish the bead with a moist spatula, pallet knife or brush.
  9. Astro PFP FR Acrylic can be over-painted with most emulsion or alkyd (gloss) paints.

 

General Guide

Minimum separations and limitations: Services (single) can be sealed as specified in the detailed drawings. Minimum separation between services and the edge of the seal within each aperture should be 10mm to allow for correct fitting of backing and seal depth. Minimum separation between apertures should be at least 30mm. For larger joint dimensions or apertures other than described in the detailed drawings, Astro PFP FR Board or Astro PFP EX Mortar should be used.

 

Supporting constructions: Flexible walls must have a minimum thickness of 75 mm and comprise steel studs or timber studs*) lined on both faces with minimum 1 layer of 12.5 mm thick boards. Rigid walls must have a minimum thickness of 75 mm and comprise concrete, aerated concrete or masonry, with a minimum density of 650 kg/m3. Rigid floors must have a minimum thickness of 150 mm and comprise aerated concrete or concrete with a minimum density of 650 kg/m3. The supporting construction must be classified in accordance with EN 13501-2 for the required fire resistance period.

*Timber studs: no part of the penetration seal may be closer than 100 mm to a stud, and minimum 100 mm of insulation of class A1 or A2 according to EN 13501-1 must be provided within the cavity between the penetration seal and the stud.
