Astro PFP FR Graphite is a premium-grade fire protection sealant developed to block the passage of fire, smoke, and gases through gaps in fire-rated walls and floors. When exposed to high temperatures, it expands to fill openings around penetrations, sealing spaces left when combustible or low-melting-point materials have been destroyed by fire.
It is particularly effective for sealing challenging services that standard fire-rated mastics cannot handle, such as large plastic pipe penetrations.
For best results, it can be applied alongside an appropriate backing material, such as stone wool or Astroflame Backing Material, to achieve the correct width-to-depth ratio and minimise shrinkage during curing. Installation guidelines outline the minimum depth and maximum joint width. The sealant activates thermally at approximately 150 °C, expanding to form an intumescent barrier that can resist the passage of fire and smoke for up to four hours.

Fire Protection Shop specialise in the supply of high-quality fire extinguishers. There are many different classifications of fire and so our products include a variety of different extinguisher types. For example, we offer water or foam fire extinguishers for solid combustibles and carbon dioxide fire extinguishers for flammable liquid or electrical fires. Each extinguishing agent comes with its benefits. Typically, water extinguishers are cheaper, produce a cooling effect and prevent reignition once the fire has been extinguished. Carbon dioxide extinguishers are clean agents, they leave no residue, are suitable for electrical fires and are often used on liquid fires which include petrol, oil or other solvents.
In addition to our extinguishers, we offer a range of fire safety products to both domestic and commercial premises. This includes the supply of fire blankets, extinguisher stands, smoke alarms, first aid kits and much more. Our entire range is sourced from reputable brand manufacturers at competitive prices. Also, all of our products carry a full warranty and guarantee and are supplied with relevant fixings where applicable.
So, for fire extinguishers, alarms and all your other fire safety needs, trust Fire Protection Shop to give you the quality, expertise and service you require.
