Polypropylene, also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. 

Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant.

 It is a white, mechanically rugged material and has a high chemical resistance. 

Polypropylene is the second-most widely produced commodity plastic and it is often used in packaging and labeling.

In 2013, the global market for polypropylene was about 55 million tonnes.
