Kutshanje, umthengi wabuza malunga nexabiso lentambo ye-danline yePP.Umthengi ngumenzi othumela iminatha yokuloba kumazwe angaphandle.Ngokuqhelekileyo, basebenzisa intambo ye-polyethylene.Kodwa intambo ye-polyethylene igudileyo kwaye ilungile kwaye kulula ukuyikhulula emva kokubopha.Inzuzo ye-PP yentambo ye-danline yinkqubo yayo yefayibha.Umsinga urhabaxa noko kwaye iqhina alityibilizi.
Ngokwethiyori, i-molecular formula yepropylene yile: CH3CH2CH3, kunye ne-molecular formula ye-ethylene: CH3CH3.
Ubume bepolypropylene buhamba ngolu hlobo lulandelayo:
— (CH2-CH (CH3) -CH2-CH (CH3) -CH2-CH (CH3)) n —-
Ubume be-polyethylene buhamba ngolu hlobo lulandelayo:
— (CH2-CH2-CH2-CH2) n —-
Inokubonwa kwisakhiwo ukuba i-polypropylene inomnye umxokelelwane wesebe kune-polyethylene.Emva kokuba intambo yenziwe, ngenxa yendima yetsheyini yesebe, intambo ye-polypropylene inamandla okuqina anamandla kune-polyethylene kwaye iqhina alityibiliki.
Intambo yePolyethylene ibhetyebhetye kwaye igudileyo kunepolypropylene, kwaye ivakala ithambile.
Ubuninzi bepolypropylene yi-0.91, kwaye ubuninzi be-polyethylene yi-0.93.Ke intambo yePE inzima kunentambo yePP.
