PLX
PLX, or Picatinny Liquid Explosive, is a liquid binary explosive, a mixture of 95% nitromethane (NM) and 5% ethylene diamine (EDA). Other amine groups can be used in replacement of ethylene diamine, such as triethylene tetramine or ethanolamine. While the previously mentioned amines, as well as many others, sensitize NM quite well, ethylene diamine has been found to be most effective.
