He aha ka polyethylene plastic kiʻekiʻe?
ʻO ka polyethylene kiʻekiʻe-density (HDPE) kahi ʻano palakiko i hōʻike ʻia e kona lakio ikaika-i-density kiʻekiʻe.

He plastic polyethylene?
ʻAe, he ʻano palakiko ka polyethylene. He polymer ia i hoʻohana nui ʻia ma nā ʻoihana like ʻole ma muli o kona mau waiwai kū hoʻokahi a me ka versatility. He mea māmā, paʻa, a maʻalahi hoʻi ka Polyethylene i hiki ke hoʻoheheʻe maʻalahi ʻia i nā ʻano like ʻole. Hana ʻia ka Polyethylene mai ka polymerization o nā monomers ethylene. He kinoea hydrocarbon ka Ethylene i loaʻa mai ke kinoea kūlohelohe a i ʻole ka petroleum. Ma o ke kaʻina hana i kapa ʻia ʻo polymerization, ua hoʻopaʻa pū ʻia nā molekala ethylene e hana i nā kaulahao lōʻihi E heluhelu hou aku …
