3M™ Fire Barrier Moldable Putty+ is designed for use as a one-part, 100% solids intumescent firestop that restores the integrity of fire-rated building construction.
The 3M™ Fire Barrier Quick Pass Device passes the ASTM E814 Fire Test Standard and is fire-rated for up to 3 hours (dependent upon system application). 3M Fire Barrier Quick Pass Devices are UL certified and Class L smoke-rated for additional life-safety protection.
The proven technology of this fire barrier product's intumescent action quickly seals off plastic pipes in a fire, and meets up to 3-hour fire and temperature ratings.
This patented intumescent wrap/strip firestops difficult through-penetrations such as plastic pipe, insulated pipe and cables. When exposed to heat, this flexible, rubber-like strip expands up to ten times its original volume, forming a very hard char.
