Ibhodi le-PPkuyinto ewuketshezi oluyi-semi-crystalline. Iqinile futhi inephuzu lokuncibilika eliphakeme kune-PE. Ngenxa yokuthi izinga lokushisa le-PP le-homopolymer lithambile kakhulu ngaphezu kuka-0C, izinto eziningi ze-PP zezentengiselwano ziyi-copolymers ezingahleliwe ezine-ethylene noma i-clamp copolymers engu-1 kuya ku-4% enokuqukethwe okuphezulu kwe-ethylene. Incane, kulula ukuyishibiliza nokuyicubungula, inokumelana okuphezulu kwamakhemikhali, ukumelana nokushisa kanye nokumelana nomthelela, ayinabo ubuthi futhi ayinambitheki, ingenye yepulasitiki ye-PP yobunjiniyela ehlangabezana nezidingo zokuvikela imvelo. Imibala eyinhloko imhlophe, umbala we-microcomputer, kanti eminye imibala nayo ingenziwa ngokwezifiso ngokwezidingo zamakhasimende. Uhla lwesicelo: imishini elwa ne-asidi ne-alkali.
Ibhodi le-PP eliqiniswe ngefayibha yengilazi (ibhodi le-FRPP): Ngemva kokuqiniswa ngefayibha yengilazi engu-20%, ngaphezu kokugcina ukusebenza okuhle kakhulu kokuqala, amandla nokuqina kuphindwe kabili uma kuqhathaniswa ne-PP, futhi linokumelana okuhle nokushisa kanye nokumelana nomthelela ophansi wokushisa, ukumelana ne-arc yokulwa nokugqwala, ukuncishiswa okuphansi. Ifaneleka kakhulu ifayibha yamakhemikhali, i-chlor-alkali, i-petroleum, i-dyestuff, i-pesticide, ukudla, imithi, imboni yokukhanya, i-metallurgy, ukwelashwa kwendle kanye neminye imikhakha.
Ibhodi le-PPH, i-beta (β)-I-PPHibhodi elingalukiwe elinezinhlangothi ezimbili. (β)-Imikhiqizo ye-PPH inokumelana okuhle kakhulu nokuguga kokushisa nomoya-mpilo, isikhathi eside senkonzo kanye nezakhiwo ezinhle zemishini. Isetshenziswe ngempumelelo ekukhiqizweni kwamapuleti, futhi ubuchwepheshe obuthuthukisiwe bungobuphambili eShayina. Le mikhiqizo ingasetshenziswa kumapuleti okuhlunga kanye nezitsha zomhluzi ojikelezayo, amabhodi okufaka amawindi epulasitiki aqiniswe ngefayibha yengilazi, isitoreji semboni ye-petrochemical, izinhlelo zokuthutha kanye nezokulwa nokugqwala, iziteshi zikagesi, ukuhlinzekwa kwamanzi, izinhlelo zokwelashwa kwamanzi kanye nokukhipha amanzi eziteshini zamanzi; kanye neziteshi zensimbi, iziteshi zikagesi Ukususwa kothuli, izinhlelo zokuwasha kanye nokungenisa umoya, njll.
