Polypropylene (PP) ndi thermoplastic yolimba, yolimba, komanso yopangidwa ndi kristalo. Imapangidwa kuchokera ku propene (kapena propylene) monomer. Utomoni wa hydrocarbon wolunjika uwu ndiye polima wopepuka kwambiri pakati pa mapulasitiki onse ogulitsa. PP imabwera ngati homopolymer kapena copolymer ndipo imatha kuwonjezeredwa kwambiri ndi zowonjezera. Imagwiritsidwa ntchito mu ma CD, magalimoto, zinthu zogulira, zamankhwala, mafilimu opangidwa ndi zinthu zina, ndi zina zotero.
PP yakhala chinthu chosankhidwa kwambiri, makamaka mukafuna polima wamphamvu kwambiri (monga, motsutsana ndi Polyamide) mu ntchito zauinjiniya kapena kungofuna phindu la ndalama m'mabotolo opangira zinthu (motsutsana ndi PET).
