Testing an Expansive Firewall Pipe Collar (Intumescent Graphite)

Here's a quick follow up to my last video about intercalated graphite and it's use in intumescent, fire resistant products (seen here:    • Fireproof Expanding Graphite  ). This pipe collar uses strips of compressed expandable graphite flake with a flexible binder to wrap around pipes and seal them off in case of fire. Pretty neat.

Thanks to Structure Tech Home Inspections for allowing me to use their footage of a successful collar test. Their video can be seen here:    • Not a flamethrower testing on intumescent ...
