Fireproof Expanding Graphite

As a result of my tests in this video: For indoor intumescent fireproofing I recommend using commercially made paints containing ammonium or melamine polyphosphate and pentaerythritol. I have not compared brand names to identify the very best fireproof paint, but several that I believe will provide very good protection are as follows:
- Contego Reactive Fire Barrier
- Firetect WT-102
- Fireguard E84
- Flameoff Fire Barrier Paint

I worked for the British Ministry of Defence. I did some crude tests on 'fire retardent foam', the sort that is used in furniture. I was VERY disapointed. Believe it or not wool as in felt was by far the best. So, a challenge for you - find a better fire retardent soft covering / filling better than wool.

I work in construction, doing telecom, and I’ve used the red putty in the video a good amount. it’s worth mentioning, that the putty has a really different application than the fireproofing paint. we use putty to stop up the sleeves we use if we need to run cable through a wall, or inside an electrical box, for other applications like sealing, they use a caulk that cures hard. the putty, at least to my understanding, only needs to stop smoke getting between rooms, or, say the insulation of your cables catches fire, to stop it using the data network to spread fire throughout the whole building, I’d be interested to see how the putty reacts when heat is applied to it while it’s inside a confined space, pack some into the end of a 1” pipe or something. I dunno if the results would be different, but they might be.

I am a fire alarm technician. The NEC requires fire putty on any sleeve passing through a firewall.

Bearing that in mind it is applied from both sides of the entry and exit point. The small flakes in the fire putty are meant to expand and drive the putty further in towards the center of the wall and also outwards towards the center of the room. Thus it compresses and seals the point from fire being able to penetrate from one side of the wall to the other.

This is an great example of the depth of information and excellent presentation that led me to support you on Patreon. I look forward to every video you make. Keep up the great work!

Nice video as always. I also was happy seeing a Robert Murray-Smith shout out. He definetly deserves more attention

[RealWunderBanana]

Honestly, I know I've said it a couple times, but you are my favorite YouTube channel. You find the coolest things that I have never even heard of or even thought about and make it into a super straight forward, awesome video.

Guys like NightHawk and TechIngredients are the true heroes of the YouTube.

Great video as ever. I did think this sort of expanding fire putty stuff was put around pipes and electrical systems, allowing them to move, but in the event of a fire, the material expanded filling any gaps and therefore stopping the spread of the fire from room to room.

The simplicity of your videos is what schools globally are missing these keep it up hawk! Love the content! Much love from Malaysia!

Robert Murray-Smith's channel is plain awesome 👏

[cvoisineaddis]

I just want to say I love this channel. It's not always about something I'm interested in but I can tell it's always something Ben was curious about or interested in and wanted to make a video.

I work with the IBEW and often use various fire proofing products. The important thing to remember about commercial fire proofing is that they all have a time rating. So perhaps the puddy with graphite flakes are good for 1 hour while the carbon foam paint is good for a longer exposure time.

Yes boy Rob got a mention, love both your channels been watching for too many years

[dfunited]

You've never led me astray with channel suggestions! Robert Murray Smith already had my subscription, but I'm sure many others will enjoy his content.

[ScottSenkeresty]

Fantastic content! And isn't Robert's love and laugh infectious!?

The smaller mesh taking longer may have something to do with surface tension. It may also have something to do with a reduction in the capillary effect. Just a thought.

I run a firestop installation business in Indonesia, watching this video provides new insight which is very important for my business, I am very grateful and appreciative to the creator of this video

Fascinating! I recently started exploring graphite use in refractory and foundry applications. Not sure how expanding graphite applies, but the information, especially graphite foil, is fascinating.

Reminds me of magic snakes from the joke shop when I was a kid. Little black pellet, you set it alight and it expands into a long 'snake'.
