Polypropylene (PP)

Polypropylene is a semi-rigid, hard plastic material that is highly scratch-resistant. It is used to make automotive parts such as bumpers, dashboards and gas tanks. It is also used to make grease-proof food packaging, heavy-duty textiles used by building trade workers, disposable work wear, cord and rope, synthetic rugs and carpeting, and upholstery fabric. It is even used for banknotes in Israel, Mexico and Australia. Chemically, polypropylene is a semi-crystalline thermoplastic whose monomer is the CH2=CH-CH3 propylene (propene).
