I-Polypropylene (PP) yi-thermoplastic eqinileyo, eqinileyo, nekristale. Yenziwe nge-propene (okanye i-propylene) monomer. Le resin ye-hydrocarbon ethe ngqo yeyona polymer ilula kakhulu kuzo zonke iiplastiki ezithengiswayo. I-PP iza njenge-homopolymer okanye njenge-copolymer kwaye inokwandiswa kakhulu ngezongezo. I-Polypropylene eyaziwa ngokuba yi-polypropene, yi-polymer ye-thermoplastic esetyenziswa kwiintlobo ngeentlobo zezicelo. Yenziwa nge-chain-growth polymerization evela kwi-monomer propylene. I-Polypropylene ikwiqela le-polyolefins kwaye i-crystalline kwaye ayi-polar. Iimpawu zayo zifana ne-polyethylene, kodwa inzima kancinci kwaye iyamelana nobushushu. Yinto emhlophe, eqinileyo kwaye inokumelana neekhemikhali eziphezulu.
