He thermoplastic paʻakikī, paʻa, a crystalline ka Polypropylene (PP). Hana ʻia ia mai ka monomer propene (a i ʻole propylene). ʻO kēia resin hydrocarbon linear ka polymer māmā loa ma waena o nā plastics waiwai āpau. Hiki mai ka PP ma ke ʻano he homopolymer a i ʻole he copolymer a hiki ke hoʻonui nui ʻia me nā mea hoʻohui. Loaʻa iā ia ka hoʻohana ʻana i loko o ka ʻōpala, kaʻa, nā waiwai mea kūʻai aku, nā lāʻau lapaʻau, nā kiʻiʻoniʻoni hoʻolei, a pēlā aku.
Ua lilo ka PP i mea koho nui ʻia, ʻoiai ke ʻimi nei ʻoe i kahi polymer me ka ikaika kiʻekiʻe (e laʻa, vs Polyamide) i nā noi ʻenekinia a i ʻole e ʻimi wale ana i ka pono kumukūʻai i nā ʻōmole hoʻoheheʻe puhi (vs. PET).
