Ua pōkole ʻia ʻo Polyethylene ʻo PE, he ʻano resin thermoplastic i hana ʻia e ka polymerization o ethylene. I loko o ka ʻoihana, hoʻokomo pū ʻia nā copolymers o ethylene a me kahi liʻiliʻi o α-olefin. ʻAʻohe ʻala o ka Polyethylene, ʻaʻohe ʻawaʻawa, manaʻo like me ka wax, loaʻa iā ia ke kūpaʻa haʻahaʻa maikaʻi loa (hiki i ka mahana hoʻohana liʻiliʻi ke hiki i -70～-100℃), loaʻa iā ia ke kūpaʻa kemika maikaʻi, a hiki ke kū i ka hapa nui o nā waikawa a me nā alkalis (ʻaʻole kū i nā waiwai oxidizing) Acid), ʻaʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe maʻamau i ka mahana o ka lumi, haʻahaʻa ka omo wai, insulation uila maikaʻi loa; akā he maʻalahi loa ka polyethylene i ke kaumaha o ke kaiapuni (nā hopena kemika a me ka mechanical), a he kūpaʻa ʻole i ka wela. ʻOkoʻa nā waiwai o ka polyethylene mai nā ʻano a i nā ʻano, ma muli o ke ʻano molekala a me ka density. Hiki ke hoʻohana ʻia nā ʻano hana like ʻole e loaʻa ai nā huahana me nā density like ʻole (0.91～0.96g/cm3). Hiki ke hana ʻia ka Polyethylene e nā ʻano hoʻoheheʻe thermoplastic maʻamau (e ʻike i ka hana plastic). Loaʻa iā ia kahi ākea o nā hoʻohana, hoʻohana nui ʻia e hana i nā kiʻiʻoniʻoni, nā ipu, nā paipu, nā monofilaments, nā uea a me nā kaula, nā mea e pono ai i kēlā me kēia lā, a me nā mea ʻē aʻe, a hiki ke hoʻohana ʻia e like me nā mea hoʻokaʻawale alapine kiʻekiʻe no nā TV, nā radar, a pēlā aku.
Nā ʻano PE:
(1) LDPE: polyethylene haʻahaʻa haʻahaʻa, polyethylene kaomi kiʻekiʻe
(2) LLDPE: polyethylene haʻahaʻa linear
(3) MDPE: polyethylene density waena, resin bimodal
(4) HDPE: polyethylene density kiʻekiʻe, polyethylene haʻahaʻa
(5) UHMWPE: Polyethylene kaumaha molekala kiʻekiʻe loa
(6) Polyethylene i hoʻololi ʻia: CPE, polyethylene i hoʻopili ʻia (PEX)
(7) ʻEthylene copolymer: ethylene-propylene copolymer (plastic), EVA, ethylene-butene copolymer, ethylene-ʻē aʻe olefin (e like me octene POE, cyclic olefin) copolymer, ethylene-unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH

ʻO kā mākou pipettehana ʻia ia me ka mea HDPE
