OVERVIEW

High-performance cable firestop mastic

Micon FLAMSAYF 325 is an advanced, fire-retardant mastic engineered to stop flame spread and toxic gas emission along PVC-armoured cables and service penetrations. When used in conjunction with mineral wool boards, it forms a fire-resistant seal that retains integrity under extreme heat for a minimum of 120 minutes

Applied by trowel, brush, or hand to a minimum 3 mm thickness, FLAMSAYF 325 delivers certified, industrial-grade protection.

OVERVIEW

Easy installation and lasting protection

Flamsayf 325 for electrical cables and penetration seals is designed to slow down the spread of fire and heat in the event of a fire. It forms a protective barrier that insulates cables and seals, reducing the risk of fire traveling through walls, floors, and ceilings. When exposed to high temperatures, the mastic typically causes a chemical reaction, maintaining the integrity of fire-rated structures. This also helps prevent smoke and toxic gases from spreading.
