MAPP Gas vs. Propane: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 22, 2024
MAPP gas is a mixture of gases used for high-temperature heating, whereas propane is a single hydrocarbon gas used for heating and fuel.

Key Differences

MAPP gas, an acronym for Methylacetylene-Propadiene Propane, was originally a mixture of methylacetylene and propadiene, whereas propane is a pure hydrocarbon gas, chemically C3H8.
MAPP gas burns at a higher temperature compared to propane, providing more heat and making it suitable for tasks requiring intense heat, like welding. Propane, on the other hand, is used in a wider range of applications, from heating to cooking, due to its lower burning temperature.
The original MAPP gas production ceased in 2008 and was replaced by MAP-Pro, a different formulation still providing higher heat than propane. Propane remains unchanged as a popular fuel choice for its availability and versatility.
MAPP gas, due to its higher burning temperature, is often preferred for metalworking that requires quick, high heat application. Propane, being more moderate in heat output, is preferred for general heating, barbecue grills, and home heating.
Safety considerations for MAPP gas include its higher combustion temperature, making it more hazardous in certain conditions. Propane, while also flammable, is considered safer for general use in home and commercial settings due to its lower combustion temperature.
