Polypropylene (PP) ipurasitiki yakasimba, yakasimba, uye ine kristalo. Yakagadzirwa kubva kumonomer yepropene (kana propylene). Iyi linear hydrocarbon resin ndiyo polymer yakareruka kupfuura mamwe mapurasitiki ese emhando yepamusoro. PP inouya sehomopolymer kana secopolymer uye inogona kuwedzerwa zvakanyanya. Polypropylene inozivikanwawo sepolypropene, ipolymer yethermoplastic inoshandiswa mumhando dzakasiyana siyana. Inogadzirwa kuburikidza nepolymerization yechain-growth kubva kumonomer propylene. Polypropylene iri muboka repolyolefins uye ine crystalline zvishoma uye isiri polar. Hunhu hwayo hwakafanana nepolyethylene, asi yakaoma zvishoma uye inodzivirira kupisa. Ichinhu chichena, chakasimba uye ine resistance yakakura yemakemikari.
