Wahi a nā helu helu mai ka pūnaewele o ka Hui Cellulose Kina, i ka makahiki 2017, ʻo ka hana kūloko o ka cellulose ether he 373,000 tons, a ʻo ka nui o ke kūʻai aku he 360,000 tons. I ka makahiki 2017, ʻo ka nui o ke kūʻai aku maoli o ka ionic CMC he 234,000 tons, he piʻi ʻana o 18.61% makahiki-ma-makahiki, a ʻo ka nui o ke kūʻai aku o ka non-ionicCMChe 126,000 tons, he piʻi ʻana o 8.2% i kēlā me kēia makahiki. Ma waho aʻe o HPMC (pae mea kūkulu hale), nā huahana non-ionic, HPMC (pae lāʻau lapaʻau),HPMC(pae meaʻai),HEC, HPC, MC, HEMC, a pēlā aku. ua kūʻē i ke ʻano a ua hoʻomau ka piʻi ʻana o kā lākou hana a me ke kūʻai aku. Ua ulu wikiwiki ka cellulose ether kūloko no nā makahiki he ʻumi a ʻoi, a ua lilo kāna hana i mea mua ma ka honua.
