1, phapang ea tšebeliso.
Sekala sa tšebeliso eaLetlapa la PE: e sebelisoa haholo indastering ea lik'hemik'hale, mechine, indasteri ea lik'hemik'hale, matla a motlakase, liaparo, liphutheloana, lijo le liindasteri tse ling. E sebelisoa haholo lipalangoang tsa khase, phepelo ea metsi, phallo ea likhoerekhoere, nosetso ea temo, lipalangoang tsa morafo tse ntle, tšimo ea oli, indasteri ea lik'hemik'hale, poso le likhokahano le masimo a mang, haholo-holo lipalangoang tsa khase.
Boemo ba tšebeliso ealeqephe la pp: lisebelisoa tse hanyetsanang le asiti le alkali, lisebelisoa tsa ts'ireletso ea tikoloho, metsi a litšila, lisebelisoa tsa ho qhala khase e litšila, tora ea ho hloekisa, kamore e hloekileng, lisebelisoa tsa lifeme tsa semiconductor le liindasteri tse amanang le tsona, hape ke thepa e ratoang bakeng sa ho etsa litanka tsa metsi a polasetiki, tseo har'a tsona ho sebelisoang lipampiri tse teteaneng tsa PP tse sebelisoang haholo bakeng sa litempe tsa litempe, poleiti ea tšehetso ea punch, joalo-joalo.
2. Phapang ea litšobotsi.
PE boarde batla e le bonolo, e na le tekanyo e itseng ea toughness, ho hanyetsa tšusumetso e ntle le ts'ebetso ea cushioning, 'me tshebetso ea boto e bōpiloeng e molemo; Boto ea PP e na le boima bo phahameng, thepa e sa sebetseng hantle ea mochini, ho tiea ho tlase, le ts'ebetso e mpe ea ho hanyetsa le ho ts'oara.
3. Phapang ea thepa.
Boto ea PP, e tsejoang hape e le letlapa la polypropylene (PP), ke thepa ea semi-crystalline. E thata ho feta 'me e na le sebaka se phahameng sa ho qhibiliha ho feta PE. Letlapa la PE ke resin e khanyang haholo, e seng polar thermoplastic. Ponahalo ea HDPE ea pele e tšoeu ea lebese, 'me karolo e tšesaane e fetoha ho isa bohōleng bo itseng.
