Ko te tātai matū koC2H4He rauemi matū taketake tēnei mō ngā muka hangai, te rapa hangai, ngā kirihou hangai (polyethylene me te polyvinyl chloride), me te etanoru hangai (waipiro). Ka whakamahia hoki hei hanga i te vinyl chloride, te styrene, te ethylene oxide, te waikawa acetic, te acetaldehyde, me ngā mea pahū. Ka taea hoki te whakamahi hei whakamāoa i ngā hua me ngā huawhenua. He homoni tipu kua whakamātauhia.

EtirenaKo tētahi o ngā hua matū nui rawa atu o te ao. Ko te umanga ethylene te uho o te umanga petrochemical. Neke atu i te 75% o ngā hua petrochemical e whakamahia ana e ngā hua ethylene, ā, he tūranga nui tō rātou i roto i te ōhanga o te motu. Kua whakamahia e te ao te hanga ethylene hei tohu nui hei ine i te taumata whanaketanga o te umanga petrochemical o tētahi whenua.
