Applications
Examples of uses of this molecule in Industry and Healthcare
Chemicals
Propene is the second most important feedstock for the petrochemical industry. Propene is the feedstock in the production of one of the most important polymer: polypropylene. It is also converted to propylene oxide, a precursor of propylene glycol and polyurethane, acrylonitrile, cumene, Oxo-alcohols, Isopropanol and acrylic acid.
Electronic components
Propene is a carbon source for amorphous carbon hard masks.
Laboratories & Research Centers
Propene is used in calibration gas mixtures for petrochemical industry, environmental emission monitoring, industrial hygiene monitors and trace impurity analyzers.
