Propylene
Formula: C3H6
C3H6 or R1270
Propylene or Propene, is a colorless, flammable, liquefied gas with a detectable odor. The dominant technology for producing propylene is steam cracking. The same technology is applied to ethane to ethylene. Propene is the second most important starting product in the petrochemical industry after ethylene. It is the raw material for a wide variety of products.
Polypropylene manufacturers consume nearly two thirds of global production. Polypropylene end uses include films, fibers, containers, packaging, and caps and closures. Propene is also used for the production of important chemicals such as propylene oxide, acrylonitrile, cumene, butyraldehyde, and acrylic acid. In industry and workshops, propene is used as an alternative fuel to acetylene in Oxy-fuel welding and cutting, brazing and heating of metal for the purpose of bending.
It has become a standard in BernzOmatic products and others in MAPP substitutes, now that true MAPP gas is no longer available.

- Used to product polypropylene plastics for injection molding
- Used to manufacture propylene oxide, acrylic acid, oxo alcohols & isopropanol
- Used to manufacture a variety of construction materials such as siding, air & moisture barrier membranes, carpet textiles, films and sheets used in insulation as well as piping
- Propylene is an attractive alternative to propane for heating and cutting due to its superior combustion performance. It is also widely used as a fuel gas for high-velocity oxygen fuel (HVOF) processes
