1. Kusiyana kwa momwe ntchito ikuyendera.
Mulingo wa kagwiritsidwe ntchito kaPepala la PE: imagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, makina, makampani opanga mankhwala, magetsi, zovala, ma CD, chakudya ndi ntchito zina. Imagwiritsidwa ntchito kwambiri poyendetsa gasi, kupereka madzi, kutulutsa zinyalala, ulimi wothirira, mayendedwe a tinthu tating'onoting'ono m'migodi, komanso m'mafakitale amafuta, makampani opanga mankhwala, positi ndi mauthenga, ndi zina zotero, makamaka poyendetsa gasi.
Mulingo wogwiritsira ntchito mbale ya PP: pazida zoteteza chilengedwe, madzi otayira ndi zida zotulutsira mpweya wotayira, nsanja yotsukira, chipinda chopanda fumbi, zida za fakitale ya semiconductor ndi mafakitale ogwirizana nayo, komanso zinthu zomwe zimagwiritsidwa ntchito popanga thanki yamadzi ya pulasitiki. Munthawi imeneyi, mbale yokhuthala ya PP imagwiritsidwa ntchito kwambiri popaka mbale, punch pad, ndi zina zotero.
2. Kusiyana kwa makhalidwe.
Bolodi la PE ndi lofewa ndipo lili ndi kulimba kwina, ndipo kukana kwake kukhudza ndi magwiridwe antchito a cushion ndi abwinoko, zomwe bolodi lopangidwa limagwira ntchito bwino; bolodi la PP lili ndi kuuma kwakukulu, mphamvu zochepa zamakanika, kulimba kochepa komanso kukana kukhudza kochepa.
3. Kusiyana kwa zinthu.
Mbale ya PP, yomwe imadziwikanso kuti mbale ya polypropylene (PP), ndi chinthu chopangidwa ndi theka-crystalline. Ndi cholimba kuposa PE ndipo chili ndi malo osungunuka kwambiri. Pepala la PE ndi mtundu wa utomoni wa thermoplastic wokhala ndi crystallinity yambiri komanso non-polarity. Mawonekedwe a HDPE yoyambirira ndi oyera ngati mkaka, ndipo amawala pang'ono m'gawo lopyapyala.
