ʻO ka polyethylene (PE, pōkole no ka PE) he resin thermoplastic i hoʻomākaukau ʻia e ka polymerization o ka ethylene.I ka ʻoihana, ua hoʻokomo pū ʻia ka copolymer o ka ethylene me kahi liʻiliʻi o ka alpha-olefin.ʻO ka polyethylene he meaʻalaʻole,ʻaʻohe meaʻawaʻawa, manaʻo e like me ka wax, me ka maikaʻi haʻahaʻa haʻahaʻa kū'ē (ʻo ka haʻahaʻa haʻahaʻa hoʻohana wela hiki ke hiki i -100 ~ -70 ° C), maikaʻi kemika paʻa, kū'ē i ka nui a me ka base erosion (ʻaʻole kū'ē i ka waika me nā mea hoʻoheheʻe).ʻAʻole hiki ke hoʻoheheʻe ʻia i ka mea hoʻoheheʻe maʻamau ma ka lumi wela, ka wai liʻiliʻi o ka wai, ka insulation uila maikaʻi.

Pilikia loa ka Polyethylene i nā koʻikoʻi o ke kaiapuni (nā hopena kemika a me ka mechanical), a ʻoi aku ka ʻino o kona pale ʻana i ka wela ma mua o nā hale kemika polymer a me nā ʻāpana i hana ʻia.Hiki ke hana ʻia ka polyethylene e like me nā thermoplastics.Hoʻohana nui ʻia, hoʻohana nui ʻia no ka hana ʻana i nā kiʻiʻoniʻoni, nā mea hoʻopihapiha, nā ipu, nā paipu, monofilament, uea a me ke kaula, nā mea e pono ai i kēlā me kēia lā, a hiki ke hoʻohana ʻia e like me ke kīwī, radar a me nā mea insulation kiʻekiʻe.
