I-Polypropylene (PP) iyi-thermoplastic eqinile, eqinile, futhi ekristalu. Yenziwe nge-propene (noma i-propylene) monomer. Le resin ye-hydrocarbon eqondile iyi-polymer elula kunazo zonke phakathi kwazo zonke ipulasitiki zezimpahla. I-PP iza njenge-homopolymer noma njenge-copolymer futhi ingathuthukiswa kakhulu ngezithasiselo. I-Polypropylene eyaziwa nangokuthi i-polypropene, iyi-polymer ye-thermoplastic esetshenziswa ezinhlotsheni eziningi zokusebenza. Ikhiqizwa nge-polymerization yokukhula kweketanga kusuka ku-monomer propylene. I-Polypropylene ingeyeqembu lama-polyolefin futhi i-crystalline kancane futhi ayiyona i-polar. Izakhiwo zayo zifana ne-polyethylene, kodwa iqinile kancane futhi imelana nokushisa. Iyinto emhlophe, eqinile ngomshini futhi inokumelana okuphezulu kwamakhemikhali.
