UltraBlue Propane?

[ancorp]

Has anyone tried this stuff in comparison to regular Coleman propane?

Says it burns twice the heat of regular propane, don't know if that makes a difference if you're using it without combustion...

1/10 the weight, and the size of a spray paint can, sounds like a good option to carry on the field for your GBB eh?

So... any ideas?

Cheers,

sounds nice......except that the top isn't threaded for a AI adapter. Same type of top on duster cans (with out the tip)

Hmm... alright I'm going to have to trust you on that. I finally grabbed a decent GBB with a propane adapter (will be here next week), so just looking at my options. Since this is a no-go, I think I have the two options of the blue torch can, and the green stove tanks...

On the other hand, couldn't one use an AI Duster adapter for this then?

Thanks,
Cheers,

Nope, it's got a valve design which does not offer a stem for a duster adaptor. I don't make an adaptor for this as this gas costs about twice the cost of coleman branded tanks and the valve standard is not widely distributed.

MadMax, just out of scientific curiousity, is the stuff in the bottle actually different from standard propane?

yes

Its mixed with chemicals that increase burn temperature. This is where my info gets sketchy I think can contents is something like 9 parts propane 1 part NO2. madmax feel free to correct me on the additive. but i now for dam fact there is one cause the burnlite(blue bottles) gives you the hottest pure propane burn to get hotter you need to add something.

It will be intresting to see what happens to a gun. When thats gun on that stuff after like 3k rounds(as well as befor and afters and durings for fps and shooting it might be a performence enhancer)

From the CT page:

Safe and inexplosive -can is foam-filled with propane contained inside the closed foam cells

Sounds like it's not just propane in there. Has anyone bought a can just to see what comes out?

Acualuy its calls the fire proof can. Stab it with a knife theres a liquid between the inner can and outer that when it comes in contact with air it expands and fire retards. built in fire extinguisher. But it also destroys the gas inside by eating it.

I'm seeing a vapour pressure of only 70PSI at a very warm 110F. Unless they made a mistake and transposed 70 with 110 (i.e. 110psi @ 70F) that's a very low pressure gas. Coleman's MSDS lists a pressure of 208psi @ 100F (http://www.coleman.com/coleman/msds/propane.pdf). Ultrablue indicates 100% alkane content on their MSDS. I am guessing that UB is a blend of butane and propane. Propylene and MAPP are not alkanes. They would have to be indicated if they are present in significant quantity. UB's high burn temperature is probably acheived with a well designed mixer in their torch head rather than by chemical means such as an included oxidizer since none is indicated in their MSDS.

I see no indications of autoextinguishing features. There are failsafe rupture features in the can base shown in patents held by the can manufacturer:

It looks like a large piece of open cell urethane foam is put inside the can to restrict fast exhausting of the contents if the rupture feature opens.

The open cell foam would permit slow permeance of contents (exhaust to torch) but would probably bunch up at the bottom if the rupture feature were to overpressurize so the can doesn't become a rocket.

That slug of foam looks pretty open cell to me. Closed cell foam wouldn't work very well. I would end up trapping the gas so it couldn't escape to power a torch.
