Description
Astro PFP FR Graphite is a premium fire-rated sealant designed to stop the spread of fire, smoke, and gases through wall and floor penetrations. It reacts to heat by expanding and sealing gaps left by burnt-out plastic pipes or insulation. Ideal for sealing tricky services like large plastic pipes, it’s easy to apply, needs no primer, and delivers a smooth, flexible finish with high sound insulation. Suitable for a wide range of materials—concrete, wood, metal, plastics, and more—it cures quickly and offers long-term durability, with a working life of up to 30 years. For best results, pair with stone wool or Astroflame backing material.
Main Features:
- Fire Protection: Expands upon fire exposure to seal gaps around plastic pipes, cables, and combustible pipe insulations, providing up to 4 hours of fire resistance.
- Ease of Application: Ready-to-use with a smooth finish; no priming required for most materials.
- Flexibility: Accommodates joint movement up to 12.5%, maintaining integrity over time.
- Environmental Safety: Low emissions, environmentally friendly, and user-safe with a 30-year working life.
- Versatility: Suitable for various surfaces, including concrete, bricks, steel, wood, gypsum, glass, plastics, and most non-porous materials.
- Quick Curing: Hardens rapidly, becoming tack-free within 1 hour
