Muva nje, ikhasimende libuze ngentengo yentambo ye-danline ye-PP.Ikhasimende lingumkhiqizi othumela amanetha okudoba kwamanye amazwe.Ngokuvamile, basebenzisa intambo ye-polyethylene.Kodwa intambo ye-polyethylene ibushelelezi futhi inhle futhi kulula ukuyikhulula ngemva kokubopha.Inzuzo ye-PP danline intambo isakhiwo sayo se-fiber.Imicu ilukhuni kanti ifindo alisheleli.
Ngokwethiyori, ifomula ye-molecular ye-propylene ithi: CH3CH2CH3, kanye ne-molecular formula ye-ethylene ithi: CH3CH3.
Isakhiwo se-polypropylene simi kanje:
— (CH2-CH (CH3) -CH2-CH (CH3) -CH2-CH (CH3)) n —-
Isakhiwo se-polyethylene simi kanje:
— (CH2-CH2-CH2-CH2) n —-
Kungabonakala esakhiweni ukuthi i-polypropylene inochungechunge olulodwa lwegatsha kune-polyethylene.Ngemva kokwenziwa kwentambo, ngenxa yendima yeketango legatsha, intambo ye-polypropylene inamandla aqinile okuqina kune-polyethylene futhi ifindo alisheleli.
Intambo ye-polyethylene ivumelana nezimo futhi ibushelelezi kune-polypropylene, futhi izwakala ithambile.
Ukuminyana kwe-polypropylene ngu-0.91, kanti ukuminyana kwe-polyethylene ngu-0.93.Ngakho Intambo ye-PE inzima kunentambo ye-PP.
