1. Ngombono wokumelana nokushisa,ukumelana nokushisa kwe-polypropylene kuphakeme kune-polyethylene.Izinga lokushisa elincibilikisa i-Polypropylene licishe libe ngu-40% -50% ngaphezu kwe-polyethylene, lingaba ngu-160-170 ℃, ngakho-ke imikhiqizo ingafakwa inzalo ngaphezu kuka-100 ℃, ngaphandle kwamandla angaphandle.Intambo ye-PP engu-150 ℃ ayikhubazekile.I-Polypropylene ibonakala ngokuminyana okuphansi, izakhiwo eziphakeme zemishini ku-polyethylene kanye nokuqina okuvelele.
2. Ngombono wokuhlaziywa kokumelana nokushisa okuphansi, ukumelana nokushisa okuphansi kwe-polypropylene kubuthakathaka kune-polyethylene, amandla omthelela angu-0 ℃ ayingxenye kuphela ye-20 ℃, futhi izinga lokushisa le-polyethylene brittle lingafinyelela -50 ℃ ngezansi;Ngokukhula kwesisindo samangqamuzana, ubuncane bungafinyelela -140 ℃.Ngakho-ke,uma imikhiqizo idinga ukusetshenziswa endaweni yokushisa ephansi, nomangangokunokwenzeka ukukhetha i-polyethylene njengento eluhlaza.
3. Ngombono wokumelana nokuguga, ukumelana nokuguga kwe-polypropylene kubuthakathaka kunokwe-polyethylene.I-Polypropylene inesakhiwo esifana ne-polyethylene, kodwa ngenxa yokuthi inochungechunge oluseceleni olwakhiwe i-methyl, kulula ukuba i-oxidized futhi yonakaliswe ngaphansi kwesenzo sokukhanya kwe-ULTRAVIOLET namandla okushisa.Imikhiqizo evame kakhulu ye-polypropylene okulula ukuguga ekuphileni kwansuku zonke izikhwama ezilukiweyo, okulula ukuphuka lapho zibekwe elangeni isikhathi eside.Eqinisweni, ukumelana nokuguga kwe-polyethylene kuphakeme kune-polypropylene, kodwa uma kuqhathaniswa nezinye izinto zokusetshenziswa, ukusebenza kwayo akuvelele kakhulu, ngoba kunenani elincane lezibopho ezimbili kanye nezibopho ze-ether kuma-molecule e-polyethylene, ukumelana nesimo sezulu akukuhle, ilanga, imvula nayo izobangela ukuguga.
4. Ngombono wokuguquguquka, nakuba i-polypropylene inamandla amakhulu, ukuguquguquka kwayo kumpofu, okubuye kube ukumelana nomthelela ongemuhle ngokombono wezobuchwepheshe.
