2. Firestop Putty is a one-part elastomeric paste with unique intumescent property, when fired against the passage of flame, noxious gas and smoke. It is used for protection of the through penetration of metal pipe and duct with 3 hours fire rating. When exposed to 1x106 Gy (1x108 rad) neutron and gamma radiation unit, it can still perform good firestop function.
4. Fire Barrier Foam is a two-part, medium-density foam supplied as A and B liquid components, which is designed to seal large opening and multiple penetrations, such as cable bundles, cable trays and metallic pipes. Before foaming, the A and B mixture is liquid type with good fluidity, which is very suitable for sealing the opening contain multiple through penetrations. Furthermore, when exposed to 1x106 Gy (1x108 rad) neutron and gamma radiation unit, it can still perform good firestop function.

3. Fire Barrier Silicone Sealant is a ready-to-use, gun-grade, one-component silicone elastomer used to seal joint system and the gaps of various through penetrations with 3 hours fire rating, which are needed to stop spread of fire, smoke and toxic gas during the fire conditions. When exposed to 1x106 Gy (1x108 rad) neutron and gamma radiation unit, it can still perform good firestop function.
