Apachi® propylene cuts at a speed that matches acetylene. What's more , cuts that are made with Apachi® propylene have a uniform kerf width, smooth surface and slag falls away easily. It is stored as a liquid and does not require containment in a stabilising medium. Apachi® propylene ignites easily in a torch but has a smaller flammable range than acetylene making leaks less hazardous. It is non-toxic and generally non-corrosive. Supplied in a 43 litre steel cylinder containing 19 kg.
