Product Description

Product Description

Both liquid and gas forms of MAPP are colorless. The gas has an obvious acetylene-like or fishy smell when the concentration is higher than 100 ppm, which is due to the addition of substituted amines as polymerization inhibitors. Low molecular weight alkynes have a strong odor. If inhaled in high concentrations, MAPP gas is toxic.

Mapp gas is a mixture of various hydrocarbons, mainly methyl acetylene, propadiene, and propane (MAPP). It generates a relatively hot flame (2,976°C) and releases high heat (15,445kJ/m 3) in the main flame (inner cone), which is lower than acetylene (18,890kJm 3), but much higher than propane ( 10,433kJm) 3). Similar to propane and natural gas, the secondary flame (outer cone) also releases high heat. Compared with acetylene, the lower flame temperature, more dispersed heat source, and larger airflow together lead to a greatly reduced perforation time.
