Electric_Light E 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? #1 · Apr 17, 2011 MAPP was offered as a drop in alternative for propane for use in portable torches to get a higher temperature.

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)." #3 · Apr 18, 2011 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. #4 · Apr 18, 2011 Too bad its $8 a canister for just a 10% higher BTU. Insert Quotes Post Reply
