Product Description
Advantages of 3M™ Fire Barrier Moldable Putty Pads MPP+
- Pliable one-part intumescent firestop material is useful for wall openings and through penetrations
- Provides draft and cold smoke seal, helps reduce noise transfer
- Firestop tested for through penetration and membrane applications for up to 4 hours in accordance with ASTM E 814 (UL 1479)
- Excellent adhesion to a wide range of construction materials
- Non-corrosive to metal, and compatible with synthetic cable jackets
- Applied by hand, with no mixing or tools
3M™ Fire Barrier Moldable Putty Pads MPP+ are a one-part firestop material that you can use in various fire-rated assemblies, such as electrical box protection. Designed to prevent the spread of fire, smoke and noxious gasses, this intumescent material comes ready to use in convenient 1/10” (2.54 mm) thick pads that are conformable by hand with no mixing or tools. 3M firestop tests these pads up to 4 hours.
Pliable, Conformable and Shapeable for Exacting Coverage
For applications requiring conformable coverage, these pliable 3M™ Fire Barrier Moldable Putty Pads MPP+ meet a full range of firestop needs that would be impractical with strips, wraps or rolls. Ready to use in convenient 1/10” (2.54 mm) thick pads, 3M designed this firestop material for excellent adhesion to most construction substrates and is non-corrosive when you apply it to metal. This makes these pads ideal for use with listed steel or plastic electrical outlet boxes. It is also safe for applications including synthetic cable jackets, making it suitable for firestopping cable bundles. It won’t crumble or dry out, exhibits excellent aging properties and is re-enterable to save time and money after installation. The pads are extremely simple and cost-effective to install. Technicians mold the material by hand directly onto the substrate without mixing or tools. For larger applications, you can mold self-adhering pads together.
Recommended Applications
- Protection of membrane penetrations for listed metallic and non-metallic electrical boxes
- Wall opening protective to meet building requirements
- Seal gaps between cables in multiple penetrations (including fiber optic inner duct)
- Insulated pipe, electrical conduit and metal pipe penetrations
Fully Tested and Approved
These intumescent 3M™ Fire Barrier Moldable Putty Pads MPP+ are firestop tested up to 4 hours in accordance with ASTM E 814 (UL 1479).
