Methylacetylene-propadiene gas explained

Methylacetylene-propadiene (MPS) gas is a type of fuel gas used in oxy-fuel welding and cutting torches, comprising a mixture of several gases.

MPS gases

An MPS gas is a mixture of two or more of propane, butane, butadiene, methylacetylene (propyne, CH₃C≡CH) and propadiene (CH₂=C=CH₂).^[1] They are marketed under different names including: "MPS", "Chem-O-Lean", "Apachi Gas", "FG-2 Gas", "Flamex" and "natural gas".^[1] The most commonly known type of MPS gas is the discontinued MAPP gas.^[2]

As a fuel gas, it burns hotter than propylene, propane or natural gas.
