Ishidi le-PP liyizinto ezi-semi-crystalline. Liqinile futhi linephuzu 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 engu-1 kuya ku-4% noma i-clamp copolymers enokuqukethwe okuphezulu kwe-ethylene.
Ishidi le-PP elihlanzekile linobukhulu obuphansi, kulula ukulishisela nokulicubungula, linokumelana kwamakhemikhali okuphezulu, ukumelana nokushisa kanye nokumelana nomthelela, alinabo ubuthi futhi alinambitheki, futhi okwamanje lingenye yepulasitiki yobunjiniyela enobungani kakhulu nemvelo. Imibala eyinhloko imhlophe, umbala we-microcomputer, kanti eminye imibala nayo ingenziwa ngokwezifiso ngokuya ngezidingo zamakhasimende. Izicelo: imishini emelana ne-asidi ne-alkali, abakhiqizi beshidi le-pp.
Ishidi elikhishwe nge-polypropylene (PP) liyishidi lepulasitiki elenziwe ngokungeza izithasiselo ezahlukahlukene ezisebenzayo ku-resin ye-PP ngokusebenzisa i-extrusion, i-calendar, i-cooling, i-cutting kanye nezinye izinqubo.
Ishidi le-PP eliqiniswe ngefayibha yengilazi (ishidi le-FRPP): Ngemva kokuqiniswa yifayibha 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.
Ishidi le-PPH lisetshenziswe ngempumelelo ekukhiqizweni kwamaphepha, futhi ubuchwepheshe obuthuthukisiwe busesikhundleni esiphambili eShayina. Le mikhiqizo ingasetshenziswa kumapuleti okuhlunga kanye nezitsha zokubopha amanxeba ezijikelezayo, kumashidi okufaka amawindi epulasitiki aqiniswe ngefayibha yengilazi, ukugcina imboni yamakhemikhali, izinhlelo zokuthutha kanye nezokulwa nokugqwala, iziteshi zikagesi, ukuhlinzekwa kwamanzi, izinhlelo zokwelashwa kwamanzi kanye nokukhipha amanzi eziteshini zamanzi; kanye neziteshi zensimbi, iziteshi zikagesi, izinhlelo zokususa uthuli, zokuwasha kanye nokungenisa umoya, njll.
