Hariho ubwoko bubiri bwingenzi bwa polypropilene irahari: homopolymers na copolymers. Abandukuzi bongeye kwigabanyamo ibice bya kopi hamwe na kopi zidasanzwe.
Buri cyiciro gihuza porogaramu zimwe kuruta izindi. Polypropilene ikunze kwitwa "ibyuma" byinganda za plastike kubera inzira zitandukanye zishobora guhindurwa cyangwa guhindurwa kugirango zikore neza intego runaka.
Ibi mubisanzwe bigerwaho mugutangiza inyongeramusaruro zidasanzwe cyangwa kubikora muburyo bwihariye. Uku guhuza n'imihindagurikire y'ikirere ni umutungo w'ingenzi.
Homopolymer polypropyleneni icyiciro rusange. Urashobora gutekereza kuri ibi nkibisanzwe imiterere ya polypropilene.Hagarika copolymerpolypropilene ifite ibice bya co-monomer bitunganijwe mubice (ni ukuvuga muburyo busanzwe) kandi birimo ahantu hose hagati ya 5% kugeza 15%.
Ethylene itezimbere ibintu bimwe na bimwe, nko kurwanya ingaruka mugihe izindi nyongeramusaruro zongera indi mico.
Kopolymer bisanzwepolypropilene - bitandukanye no guhagarika copolymer polypropilene - ifite ibice bya co-monomer bitunganijwe muburyo budasanzwe cyangwa butunguranye kuri molekile ya polypropilene.
Mubisanzwe bashizwemo nahantu hose hagati ya 1% kugeza 7% etylene kandi batoranijwe kubisabwa aho hifuzwa ibicuruzwa byoroshye, bisobanutse.
