Polypropylene vs. Polyolefin — What's the Difference?

A fabric of fibers made from any of these polymers.

A polyolefin is a type of polymer with the general formula (CH2CHR)n. They are derived from a handful of simple olefins (alkenes).

Polypropylene (PP), 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.

(chemistry) A polymer (such as polyethylene) made by the polymerization of an olefin

A synthetic resin which is a polymer of propylene, used chiefly for films, fibres, or moulding materials

(chemistry) A polyene

Any of various thermoplastic polymers of propylene. They are hard and tough, and are used to make molded articles and fibers.

A thermoplastic resin made by the polymerization of propylene, and used for films, fibres, or moulding materials. Also known as polypropene.

A polymer of propylene used as a thermoplastic molding material
