1. Umahluko kwindlela esetyenziswa ngayo.
Isikali sokusetyenziswa kwepleyiti ye-PE: sisetyenziswa kakhulu kushishino lweekhemikhali, oomatshini, kushishino lweekhemikhali, kumbane, kwiimpahla, ekupakisheni, ekutyeni nakwezinye iindawo. Sisetyenziswa kakhulu ekuthuthweni kwegesi, kubonelelo lwamanzi, kwilindle, ekunkcenkcesheleni kwezolimo, ekumbeni uthutho oluqinileyo lwamasuntswana amancinci, kunye nentsimi yeoyile, kushishino lweekhemikhali nakwiposi kunye nonxibelelwano, ingakumbi ekuthuthweni kwegesi.
Isikali sokusetyenziswa kwepleyiti ye-PP: izixhobo zokumelana ne-asidi kunye ne-alkali, izixhobo zokukhusela okusingqongileyo, amanzi amdaka, izixhobo zokukhupha igesi emdaka, inqaba yokuhlamba, igumbi elicocekileyo, umzi-mveliso we-semiconductor kunye nezixhobo zoshishino ezinxulumene noko, ikwalukhetho lokuqala lokuvelisa itanki yamanzi yeplastiki, ipleyiti etyebileyo ye-pp isetyenziswa kakhulu kwipleyiti yokubhoboza, ipleyiti yokubhoboza njalo njalo.
2. Umahluko kwiimpawu.
Ipleyiti ye-PE ithambile, inobulukhuni obuthile, ukumelana neempembelelo kwaye ukusebenza kwe-buffer kungcono, ukusebenza kwepleyiti ebunjiweyo kungcono; ubulukhuni obuphezulu bebhodi ye-PP, iipropati zoomatshini azilunganga, ubulukhuni obuphantsi, i-buffer yempembelelo embi.
3. Umahluko kwizinto ezisetyenziswayo.
Ibhodi yePP, ekwaziwa ngokuba yibhodi yepolypropylene (PP), yinto enemibala ecacileyo. Inzima kune-PE kwaye inendawo yokunyibilika ephezulu. Iphepha le-PE liyikristale ephezulu, i-non-polar thermoplastic resin. Imbonakalo ye-HDPE yokuqala imhlophe njengobisi, kwaye inombala othile ocacileyo kwicandelo elincinci.
