Hoʻokaʻawale pinepine ʻia ka Polyethylene i loko o kekahi o nā hui nui, ʻo ka mea maʻamau o ia mau mea ʻo LDPE, LLDPE, HDPE, a me Ultrahigh Molecular Weight Polypropylene. ʻO nā ʻano ʻē aʻe e komo pū me 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), Very-low-density polyethylene (VLDPE), a me Chlorinated polyethylene (CPE).
He mea palupalu loa ka Low-Density Polyethylene (LDPE) me nā waiwai kahe kū hoʻokahi e kūpono ai no nā ʻeke kūʻai a me nā noi ʻili plastik ʻē aʻe. He kiʻekiʻe ka ductility o ka LDPE akā haʻahaʻa ka ikaika tensile, kahi i ʻike ʻia ma ke ao maoli e kona ʻano e kīkoʻo i ka wā e hoʻopaʻa ʻia ai.
Ua like loa ka Linear Low-Density Polyethylene (LLDPE) me LDPE, akā hāʻawi i nā pono hou aʻe. ʻO ke kikoʻī, hiki ke hoʻololi ʻia nā waiwai o LLDPE ma ka hoʻoponopono ʻana i nā ʻāpana formula, a ʻo ke kaʻina hana holoʻokoʻa no LLDPE he emi iki ka ikehu ma mua o LDPE.
He palakika paʻa a ʻoʻoleʻa iki ka High-Density Polyethylene (HDPE) me kahi ʻano crystalline polyethylene-hdpe-trashcan-1 kiʻekiʻe. Hoʻohana pinepine ʻia ia i loko o ka palakika no nā pahu waiū, nā mea holoi lole, nā ʻōpala, a me nā papa ʻokiʻoki.
ʻO ka Ultrahigh Molecular Weight Polyethylene (UHMW) kahi mana paʻa loa o ka polyethylene, me nā kaumaha molekala maʻamau he kauoha o ka nui ma mua o HDPE. Hiki ke milo ʻia i loko o nā kaula me nā ikaika tensile i nā manawa he nui ʻoi aku ka nui ma mua o ke kila a hoʻokomo pinepine ʻia i loko o nā ʻaʻahu pale pōkā a me nā lako hana kiʻekiʻe ʻē aʻe.
