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. ʻO ka polypropylene i kapa ʻia ʻo polypropene, he polymer thermoplastic i hoʻohana ʻia i nā ʻano noi like ʻole. Hana ʻia ia ma o ka polymerization ulu ʻana o ke kaulahao mai ka propylene monomer. No ka hui o polyolefins ka polypropylene a he ʻāpana crystalline a me ka polar ʻole. Ua like kona mau waiwai me ka polyethylene, akā ʻoi aku ka paʻakikī a ʻoi aku ka wela. He mea keʻokeʻo keʻokeʻo me ka mechanically a he kiʻekiʻe ke kū'ē kemika.
