I nā makahiki i hala iho nei, ua ʻike ʻia ʻo Petroleum Resin ʻaʻole hiki ke hoʻohana pono ʻia nā dimer o dicyclopentadiene (CPD) a me methylcyclopentadiene (MCPD) ma C9, ʻo Petroleum Resin ka hopena o ka pau ʻana o nā kumuwaiwai. No ka mea, hoʻohana nui ʻia ka dicyclopentadiene i ka hana ʻana i nā lāʻau lapaʻau, pesticides, Petroleum Resin a me nā huahana resin; Hoʻohana nui ʻia ka methyl dicyclopentadiene ma ke ʻano he kumu waiwai no ka hana ʻana i ka wahie rocket kiʻekiʻe, plasticizers, Petroleum Resin a me nā mea mālama lāʻau, Petroleum Resin a he mea nui ia i nā kānaka.
He ākea ka manaʻolana o ka hoʻohana piha ʻana i ka resin petroleum c9. I ʻOkakopa 2015, ua hoʻonui ʻia ka nui o ka petroleum resin i kēlā me kēia mahina, Petroleum Resin ma muli o nā kumu aʻe: ʻai. I loko o ka mahina, ua emi iho ke kumu kūʻai o ka waiwai maka C5 ka Petroleum Resin, a ua lohi ka hoʻokipa o lalo. ʻAʻole lawa ka noi no ka petroleum resin, a hoʻomau ka emi ʻana o nā hana a nā mea hana. No laila, ʻo ka Petroleum Resin ke kumu kūʻai haʻahaʻa he waiwai nui nō hoʻi no ka hoʻoiho ʻana. ʻO ke kolu, ʻo ka Petroleum Resin ka emi ʻana o ke kumukūʻai kūʻai o RMB i ka Euro ua hoʻopōmaikaʻi i ka lawe ʻana aku i nā kumuwaiwai kūloko.
I ka nānā ʻana i ka mākeke, ʻo ka hoʻoilo ke kau haʻahaʻa kuʻuna no ka mākeke resin petroleum home. Eia kekahi, ʻo Petroleum Resin ma muli o ke kūlana hoʻokele waiwai, ʻoi aku ka nui o nā terminal a me nā pani ʻana i lalo. No laila, hoʻemi ka mākeke i ke kaomi waiwai ma o ka lawe ʻana aku. ʻO ke kumu kūʻai haʻahaʻa o C5 he kumu maikaʻi nō hoʻi; ʻO ka Petroleum Resin ka pahu a me ka pani ʻana i lalo he nui loa, Petroleum Resin e hoʻonui a emi iho ka nui o ka lawe ʻana mai.
