He kirihou wera pakari, pakari, he tioata hoki te polypropylene (PP). He mea hanga mai i te monomer propene (propylene rānei). Ko tēnei kapia hauwaiwai rārangi te polymer māmā rawa atu i roto i ngā kirihou taonga katoa. Ka puta mai te PP hei homopolymer, hei copolymer rānei, ā, ka taea te whakanui ake mā te whakamahi i ngā tāpiringa. Ka kitea te whakamahinga i roto i ngā takai, ngā motuka, ngā taonga kaihoko, ngā kiriata hauora, ngā kiriata whakarewa, me ētahi atu.
Kua noho te PP hei rauemi whiriwhiri, inā koa mēnā kei te rapu koe i tētahi pūmua he kaha ake (hei tauira, ki te whakataurite ki te Polyamide) i roto i ngā mahi hangarau, ki te rapu noa rānei i tētahi painga utu mō ngā pounamu whakarewa pupuhi (ki te whakataurite ki te PET).
