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.

Materials compatibility
Recommendations : Air Liquide has gathered data on the compatibility of gases with materials to assist you in evaluating which materials to use for a gas system. Although the information has been compiled from what Air Liquide believes are reliable sources (International Standards: Compatibility of cylinder and valve materials with gas content; Part 1- Metallic materials: ISO11114-1 (March 2012), Part 2 - Non-metallic materials: ISO11114-2 (April 2013), it must be used with extreme caution and engineering judgement. No raw data such as these can cover all conditions of concentration, temperature, humidity, impurities and aeration. It is therefore recommended that this table is only used to identify possible materials for applications at high pressure and ambient temperature. Extensive investigation and testing under the specific conditions of use need to be carried out to validate a material selection for a given application.
