MAPP gas is a fuel gas that is a better substitute for acetylene and is widely regarded as safer and easier to use than acetylene. It is a trademarked name belonging to The Linde Group, a division of the former global chemical giant Union Carbide. MAPP gas is based on a stabilized mixture of methylacetylene, propadiene, and propane. The name comes from the original chemical composition, methylacetylene-propadiene propane. MAPP gas is also widely used as a generic name for UN 1060 stabilized methylacetylene-propadiene. Genuine MAPP gas can be used in combination with oxygen for heating, soldering, brazing, and even welding because of its high flame temperature of 2925 °C (5300 °F) in oxygen. Although acetylene has a higher flame temperature (3160 °C, 5720 °F), MAPP has the advantage that it requires neither dilution nor special container fillers during transport, allowing a greater volume of fuel gas to be transported at the same given weight, and it is much safer in use. However, true MAPP gas production ended in North America in early 2008 when production was discontinued at the only remaining plant in North America that still manufactured it. Many current products labeled "MAPP" are, in fact, MAPP substitutes. These versions contain mostly propylene with some propane, and dimethyl ether is included as a third ingredient in some versions.
