Propylene (R1270)
C3H6
Propylene (R1270) is supplied as a liquid under its own vapour pressure in cylinders and in T50 ISO containers for international transport as well as road trailers and rail cars. It is generally used in commercial and industrial refrigeration applications such as LNG liquefaction and is a replacement for R22 and R502.
