Real MAPP Vs Replacement Propylene High Temp Gas?


MAPP was offered as a drop in alternative for propane for use in portable torches to get a higher temperature. It is a patented product and the only company making it decided to discontinue in 2008.

It was a blend of methyl acetylene and propane.

Now they have a substitute that's basically pure propylene.

How do they compare?

Re: Real MAPP Vs Replacement Propylene High Temp Gas?


I still have a partial case of the actual MAPP cylinders on hand, so at the rate I use it, I probably won’t actually need to buy the newer MAP/Pro propylene stuff for quite some time.

But, here is what Thermadyne, the parent company of Victor/TurboTorch, has to say about it.

MAP//PRO, which is produced by Worthington Cylinders of Columbus, OH, has a higher flame temperature and better combustion intensity than propane, which enables professional users to complete their tasks more quickly. MAP//PRO also has a higher vapor pressure than MAPP resulting in better performance in colder temperatures.
"The effective BTU output is a measurement of the quantity of BTUs that actually go into the work piece when heated", said Paul Minter, VP / General Manager, TurboTorch."Our lab tests have revealed that MAP//PRO has approximately a 10% greater BTU output over Propane and a 14% less effective BTU output than MAPP. Given the technical advancements offered by TurboTorch products as the premium brand in the market, our torches maximize the performance of propylene based (MAP//PRO)."

I've used the propleyne recently. I had good success with it, evenly heating some brass fixtures. Something I've struggled doing with propane.

It's not Mapp but it's definitely better than propane.

Too bad its $8 a canister for just a 10% higher BTU.
