Polypropylene (
PP), also known as
polypropene, is a
thermoplastic polymer used in a wide variety of applications including
packaging and labeling,
textiles (e.g.,
ropes, thermal underwear and carpets),
stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and
polymer banknotes. An
addition polymer made from the monomer
propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.
