General Characteristics Propylene is manufactured by pyrolysis of oil fractions. It is a colourless, non-toxic, extremely combustible, easily inflammable gas.
CAS: 115-07-01
Propylene is used as a monomer for the production of polymers (polypropylene and its copolymers), intermediate product for the production of chemical substances (oxoalcohols, acrylic acid) and as a technical gas for welding, cutting, etc.
The product is classified as hazardous pursuant to
Regulation (EC) No 1272/2008 CLP.

Packaging, Storage, Transportation
Liquid propylene is stored in tightly closed tanks and is transported in railway tanks. Both the railway and storage tanks are made from low-temperature steel, cooled bellow propylene boiling point or pressurized.
