> Product Description
Astro PFP FR Graphite is a high specification formulation designed to prevent the spread of fire, smoke and gases through openings in fire rated walls and floors. Astro PFP FR Graphite expands when it is subjected to fire and closes openings around penetrations when any combustible or low temperature melting materials have burnt away.
Astro PFP FR Graphite is designed to fire seal difficult services which traditional fire rated mastics do not achieve such as large plastic pipes.
Astro PFP FR Graphite can be used with a suitable filling material, i.e. stone wool or Astroflame Backing material in order to ensure 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 150 °C when the material will expand (intumesce) to prevent the passage of fire and smoke for periods up to 4 hours.
> Sound Insulation
| Description | Sound reduction |
| Single sided seal ≥ 25mm depth | Rw 53 dB |
| Double sided seal ≥ 25mm depth | Rw > 53 dB |
Astro PFP FR Graphite has been tested at EXOVA BM Trada (UKAS accredited); according to EN ISO 10140-2:2010. Usage of any backing material is optional, due to the tests being conducted with sealant only.

> 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) Astroflames'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.

All interested parties, designer, specifier, main contractor and specialist installers should provide access to allow the fire stopping seals to be regularly inspected and maintained, as well as records kept of such maintenance at minimum periods of 12 months, as required by the Regulatory Reform Order, and repaired if necessary. Reference should be made to ASFP TGD 17 – Code of Practice for the Installation and Inspection of Fire Stopping.
> Competency
It is vital that those entrusted to design or install a fire stopping product have the necessary levels of competence to undertake the task professionally and thoroughly. The level of competency required will be commensurate with the expected complexity of the building. All designers must eliminate, reduce or control foreseeable risks that may arise during installation, construction or maintenance when preparing or modifying designs. Clients should ensure that the principal designer and principal contractor carry out their duties under CDM regulations. The ASFP foundation course in passive fire protection provides essential knowledge as part of demonstrating competency and understanding in this key fire protection specialism.
