Hoʻokaʻawale ʻia ka Polyethylene i loko o kekahi o nā pūhui nui, ʻo ka mea maʻamau ka LDPE, LLDPE, HDPE, a me Ultrahigh Molecular Weight Polypropylene. ʻO nā ʻano ʻē aʻe he Medium Density Polyethylene (MDPE), Ultra-low-molecular-weight polyethylene (ULMWPE a i ʻole PE-WAX), High-molecular-weight polyethylene (HMWPE), High-density cross-linked polyethylene (HDXLPE), Cross-linked polyethylene (PEX a i ʻole XLPE), polyethylene haʻahaʻa haʻahaʻa loa (VLDPE), a me ka polyethylene Chlorinated (CPE).
ʻO ka Polyethylene Low-Density (LDPE) he mea maʻalahi loa me nā waiwai kahe ʻokoʻa e kūpono ai i nā ʻeke kūʻai a me nā noi kiʻiʻoniʻoni ʻē aʻe. Loaʻa i ka LDPE ka ductility kiʻekiʻe akā haʻahaʻa ka ikaika tensile, i ʻike ʻia i ka honua maoli e kona makemake e hoʻolōʻihi i ka wā i hoʻopaʻa ʻia.
Ua like loa ka Linear Low-Density Polyethylene (LLDPE) me LDPE, akā hāʻawi i nā mea maikaʻi. Hiki ke hoʻololi ʻia nā waiwai o LLDPE ma ka hoʻoponopono ʻana i nā mea hoʻohālikelike, a ʻo ke kaʻina hana holoʻokoʻa no LLDPE ʻoi aku ka liʻiliʻi o ka ikehu ma mua o LDPE.
ʻO ka Polyethylene High-Density (HDPE) he palaki paʻa, ʻoʻoleʻa haʻahaʻa me kahi ʻano crystalline polyethylene-hdpe-trashcan-1. Hoʻohana pinepine ʻia i loko o ka plastic no nā pahu waiu, ka mea holoi lole, nā ʻōpala, a me nā papa ʻoki.
ʻO ka Ultrahigh Molecular Weight Polyethylene (UHMW) he ʻano paʻa loa o ka polyethylene, me nā kaumaha molekala ma ke ʻano he ʻoi aku ka nui ma mua o HDPE. Hiki ke wili ʻia i loko o nā kaula me nā ikaika tensile i nā manawa he nui ma mua o ke kila a hoʻokomo pinepine ʻia i loko o nā lole pale pale a me nā mea hana kiʻekiʻe.
