1, kusiyana kwa ntchito.
Mlingo wogwiritsa ntchitoPE pepala: amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, makina, makampani opanga mankhwala, mphamvu zamagetsi, zovala, ma CD, chakudya ndi mafakitale ena. Amagwiritsidwa ntchito kwambiri mu kayendedwe ka gasi, madzi, kutulutsa zimbudzi, ulimi wothirira, migodi yabwino, kayendedwe ka mafuta, mafakitale a mankhwala, positi ndi ma telecommunications ndi zina, makamaka pa kayendedwe ka gasi.
Kuchuluka kwa ntchitopp pepala: zida zolimbana ndi asidi ndi zamchere, zida zoteteza chilengedwe, madzi otayira, zida zotayira gasi, nsanja yotsuka, chipinda choyera, zida zamafakitale opangira ma semiconductor ndi mafakitale ofananira, komanso ndi zinthu zomwe amakonda kupanga akasinja amadzi apulasitiki, omwe PP wandiweyani mapepala amagwiritsidwa ntchito kwambiri Kugwiritsidwa ntchito popondaponda mbale, nkhonya yochirikiza mbale, etc.
2. Kusiyana kwa makhalidwe.
PE boardndi ofewa, ali ndi mlingo wina wa kulimba, bwino kukana ndi cushioning ntchito, ndi ntchito ya bolodi kuumbidwa bwino; PP board ili ndi kuuma kwakukulu, kusachita bwino kwamakina, kulimba kocheperako, komanso kusagwira bwino ntchito komanso kupindika.
3. Kusiyana kwa zipangizo.
PP gulu, wotchedwanso polypropylene (PP) pepala, ndi theka-crystalline chuma. Ndizovuta komanso zimakhala ndi malo osungunuka kwambiri kuposa PE. Pepala la PE ndi utomoni wonyezimira kwambiri, wopanda polar thermoplastic resin. Maonekedwe a HDPE yoyambirira ndi yoyera yamkaka, ndipo gawo lopyapyala limatuluka pang'onopang'ono.
