General Characteristics 

Propylene is manufactured by pyrolysis of oil fractions. It is a colourless, non-toxic, extremely combustible, easily inflammable gas.

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.
