Vuba aha, umukiriya yabajije igiciro cyumugozi wa polypropilene, umukiriya ni uruganda rukora ibicuruzwa byoherezwa mu mahanga, ubusanzwe bikoreshwa ni umugozi wa polyethylene, ariko umugozi wa polyethylene uroroshye cyane, byoroshye kurekura nyuma yo gupfundika, kandi ibyiza byumugozi winsinga ni uko the monofilament yumugozi irakomeye, ipfundo ntabwo byoroshye kunyerera.Ariko polypropilene iremereye kuruta polyethylene.Mubyukuri, formula ya molekile ya propylene ni CH3CH2CH3, naho molekile ya Ethylene ni CH3CH3.Polypropilene ifite atome imwe ya karubone kurusha polyethylene, bityo ubwinshi bwumugozi wa polypropilene buremereye kuruta polyethylene.

Imiterere ya polyethylene niyi ikurikira:

- (CH2-CH2-CH2-CH2) n—-

Imiterere ya polypropilene niyi ikurikira:

- (CH2-CH (CH3) -CH2-CH (CH3) -CH2-CH (CH3)) n—-

Birashobora kugaragara uhereye kumiterere ko polypropilene ifite urunigi rwishami kuruta polyethylene.Nyuma yo gukora umugozi, kubera uruhare rwumunyururu wishami, umugozi wa polypropilene ufite impagarara zikomeye kuruta polyethylene, kandi ntibyoroshye kunyerera.Ubucucike bwa polypropilene ni 0,91 naho ubucucike bwa polyethylene ni 0,93, bityo polyethylene igomba kuba iremereye.

Umugozi wa polyethylene uroroshye, woroshye kandi woroshye kuruta polypropilene.
