Polypropylene, also known as polypropene, is a thermoplastic polymer, made by the chemical industry and used in a wide variety of applications. It is an addition polymer made from the monomer propylene, and is rugged and unusually resistant to many chemical solvents, bases and acids.

There are three general types of polypropylene: homopolymer, random copolymer and block copolymer. The comonomer used is typically ethylene. Ethylene-propylene rubber or EPDM added to polypropylene homopolymer increases its low temperature impact strength. Randomly polymerized ethylene monomer added to polypropylene homopolymer decreases the polymer crystallinity and makes the polymer more transparent.
