Ọkwa njupụta polyethylene dị elu
HDPE ọkpọkọ nwere nkesa obosara ma ọ bụ bimodal nke ịdị arọ molekụla.Ọ nwere ike na-akpụ akpụ na-eguzogide na ezi itule nke rigidity na siri ike.Ọ na-adịgide adịgide ma nwee obere sag mgbe a na-edozi ya.Ọkpụkpọ a na-emepụta site na iji resin a nwere ike dị mma, nkwụsi ike na nguzogide mmetụta yana ezigbo ihe onwunwe nke SCG na RCP.
Ekwesịrị ịchekwa resin n'ụlọ nkwakọba ihe kpọrọ nkụ na ebe ọkụ na ìhè anyanwụ.E kwesịghị ikpokọta ya na mbara ikuku.N'oge njem, ihe ahụ ekwesịghị ikpughe ìhè anyanwụ ma ọ bụ mmiri ozuzo siri ike ma ghara ibugharị ya na ájá, ala, metal scrap, coal ma ọ bụ iko.Amachibidoro ibufe ya na ihe na-egbu egbu, ihe na-emebi emebi na ire ọkụ.
