A graphite-based, largely inorganic, flexible, fire resistive, intumescent wrap designed to firestop plastic pipe penetrations in fire-rated walls, floors and floor/ceiling assemblies. The unique, intumescent property of this material means that as penetrating items such as plastic pipe are consumed by fire, 3M™ Fire Barrier Ultra GS Wrap Strip expands to maintain a tight seal, preventing the spread of fire, deadly smoke and other by-products of combustion.
- Intumescent: expands when heated to seal around items consumed by fire
- UL approved for up to 3 hour fire ratings when tested in accordance with ASTM E 814 (UL1479)
- Excellent flexibility and versatility
- Thermal insulator and smoke seal
