Protecta FR Graphite Intumescent Sealant - 310ml

Protecta FR Graphite is your go-to solution for fire sealing difficult service penetrations where traditional mastics fall short. It’s specifically designed to handle large plastic pipes, cables, and other combustible services that pass through fire-rated walls and floors. When exposed to fire from 150°C, the graphite formula activates and expands, crushing the melting plastic pipe and closing the opening to prevent the passage of fire, smoke, and hot gases for up to 4 hours.

With excellent flexibility, high sound insulation, and a 30-year working life, this sealant delivers certified performance and long-term reliability on site. It's an essential product for ensuring compliance and effective passive fire protection in modern buildings.
