1. Umehluko ekusetshenzisweni.
Izinga lokusetshenziswa kweIshidi le-PE: isetshenziswa kabanzi embonini yamakhemikhali, imishini, imboni yamakhemikhali, ugesi, izingubo, ukupakisha, ukudla kanye neminye imisebenzi. Isetshenziswa kabanzi ekuthuthweni kwegesi, ekuhlinzekweni kwamanzi, ekukhishweni kwendle, ekuniseleni kwezolimo, ekuthuthweni kwezinhlayiya ezincane eziqinile ezimayini, kanye nasensimini kawoyela, imboni yamakhemikhali, eposini nasezokuxhumana, njll., ikakhulukazi ekuthuthweni kwegesi.
Isikali sokusetshenziswa kwepuleti le-PP: lemishini engamelani ne-asidi ne-alkaline, imishini yokuvikela imvelo, imishini yokukhipha amanzi amdaka kanye negesi engcolile, umbhoshongo wokuklwebha, igumbi elingenalo uthuli, imishini yefektri ye-semiconductor kanye nezimboni ezihambisana nayo, kanye nezinto ezikhethwayo zokwenza ithangi lamanzi lepulasitiki. Phakathi nalesi sikhathi, ipuleti elijiyile le-PP lisetshenziswa kabanzi epuletini lokunyathela, i-punch pad, njll.
2. Umehluko ezimfanelweni.
Ibhodi le-PE lithambile futhi linokuqina okuthile, futhi ukumelana kwalo nomthelela kanye nokusebenza kahle kokusika kungcono, lapho ibhodi elibunjiwe lisebenza kangcono; ibhodi le-PP linokuqina okuphezulu, izakhiwo ezimbi zemishini, ukuqina okuphansi kanye nokumelana okuncane nomthelela.
3. Umehluko ezintweni zokwakha.
Ipuleti le-PP, elaziwa nangokuthi ipuleti le-polypropylene (PP), liyinto e-semi-crystalline. Liqinile kune-PE futhi linephuzu lokuncibilika eliphakeme. Ipuleti le-PE liwuhlobo lwe-resin ye-thermoplastic ene-crystallinity ephezulu kanye ne-non-polarity. Ukubukeka kwe-HDPE yokuqala kumhlophe njengobisi, futhi kukhanye ngezinga elithile esigabeni esincane.
