MRF RTV Firestop Foam

Product Description

MRF RTV Firestop Foam

This two-component RTV silicone foam features excellent crack-and-void filling capabilities and provides high resilience to accommodate vibration. MRF is designed as a seal for both deck and bulkhead pipe penetrations, which when properly mixed, expands 2 to 4 times its original volume, filling available spaces and forming an effective barrier against fire, smoke, hot gas and water penetration.

  • Excellent water resistance, adhesion and smoke seal.
  • Uniform cell structure ensures reproducible results every time. No charts to check!
  • Minimal pressure during foaming virtually eliminates shrinkage
  • Elastic properties readily accommodate minor vibration of pipe and conduit
  • Soft setting foam for easy retrofitting of cables.
