1. Umehluko ekusetshenzisweni.
Isikali sokusetshenziswa kwepuleti le-PE: sisetshenziswa kabanzi embonini yamakhemikhali, imishini, imboni yamakhemikhali, amandla kagesi, izingubo, ukupakisha, ukudla neminye imisebenzi. Sisetshenziswa kabanzi ekuthuthweni kwegesi, ekuhlinzekweni kwamanzi, endle, ekuniseleni kwezolimo, ekumbeni ukuthuthwa okuqinile kwezinhlayiya ezincane, kanye nasensimini kawoyela, imboni yamakhemikhali kanye nezokuxhumana ngeposi kanye nezokuxhumana, ikakhulukazi ekuthuthweni kwegesi.
Isikali sokusetshenziswa kwepuleti le-PP: imishini yokumelana ne-asidi ne-alkali, imishini yokuvikela imvelo, amanzi amdaka, imishini yokukhipha igesi engcolile, umbhoshongo wokuwasha, igumbi elihlanzekile, ifektri ye-semiconductor kanye nemishini yezimboni ehlobene nayo, futhi kuyindlela yokuqala yokukhiqiza ithangi lamanzi lepulasitiki, ipuleti elijiyile le-pp lisetshenziswa kabanzi epuletini lokubhoboza, epuletini lokubhoboza njalonjalo.
2. Umehluko ezimfanelweni.
Ipuleti le-PE lithambile, linokuqina okuthile, ukumelana nokushayisana kanye nokusebenza kwe-buffer kungcono, ukusebenza kwepuleti elibunjiwe kungcono; ubulukhuni obukhulu bebhodi le-PP, izakhiwo zemishini azilungile, ubulukhuni obuphansi, i-buffer yokushayisana embi.
3. Umehluko ezintweni zokwakha.
Ibhodi le-PP, elaziwa nangokuthi ibhodi le-polypropylene (PP), liyinto e-semi-crystalline. Liqinile kune-PE futhi linephuzu lokuncibilika eliphakeme. Ishidi le-PE liyi-crystallinity ephezulu, i-non-polar thermoplastic resin. Ukubonakala kwe-HDPE yokuqala kumhlophe njengobisi, ngezinga elithile lokukhanya engxenyeni encane.
