Description

MAPP Gas is a stabilized mixture of methylacetylene and propadiene. Alkane and alkene hydrocarbons are added as stabilizers. The stabilizers serve to render the methylacetylene and propadiene shock insensitive and to ensure that their concentrations remain nearly uniform at all times during vaporization of the mixture.
MAPP Gas is transported and stored as a liquid under its own vapor pressure. Its transportation, storage, and handling characteristics are the same as those of liquefied petroleum gas. It has a characteristic odor detectable at concentrations as low as 100 ppm in air. Stabilized liquefied MAPP Gas and MAPP Gas vapor are insensitive to shock.
Its vapor is not subject to exothermic decomposition from a 100-J energy source to 419°F (215°C) and 285 psig (1970 kPa). With a probe temperature of 825°F (441°C), the gas is stable up to 600°F (316°C) and 1100 psig (7580 kPa). Thus, it can be safely used up to full cylinder pressure.
