ʻO ka Polypropylene (PP) he mea ʻoluʻolu, ʻoʻoleʻa, a me ka crystalline thermoplastic. Hana ʻia ia mai ka propene (a i ʻole propylene) monomer. ʻO kēia linear hydrocarbon resin ka polymer māmā loa ma waena o nā plastic commodity āpau. Hele mai ʻo PP ma ke ʻano he homopolymer a i ʻole copolymer a hiki ke hoʻonui nui ʻia me nā mea hoʻohui. Loaʻa iā ia ka noi i ka hoʻopili, automotive, mea kūʻai maikaʻi, lāʻau lapaʻau, kiʻi ʻoniʻoni, etc.
Ua lilo ʻo PP i mea koho, ʻoiai ke ʻimi nei ʻoe i ka polymer me ka ikaika kiʻekiʻe (e laʻa, vs Polyamide) i nā noi ʻenekinia a i ʻole ke ʻimi wale ʻana i ke kumu kūʻai ma nā ʻōmole puhi puhi (vs. PET).
