E thehiloe ka 2004, Precise New Material (PNM) e sebetsa ka ho khetheha ka li-colorants bakeng sa mebala ea polasetiki. Lihlahisoa tsa rona li kenyelletsa organic pigment, dae e qhibilihisang, ho lokisa pigment le mono masterbatch (SPC). Lilemong tse 20 tse fetileng, PNM e ikemiselitse ho sebelisa li-colorants tse sebetsang ka resin. Hona joale PNM e se e le sebapali se seholo sa lidae le li-pigment tse nang le tlhahiso ea selemo le selemo ea lithane tse 5,000, matla a holimo ke lithane tse 8,000 tsa mebala ea phofo, le lithane tse fetang 6,000 tsa litokisetso tsa pigment le mono masterbatch. Re fana ka litharollo tsa bohlokoa bakeng sa bareki ba bangata ba tsebahalang lefatšeng ka bophara, 'me re fana ka litšebeletso tsa boleng bo phahameng bakeng sa bareki ba nang le pono ea machaba! Hajoale, lihlahisoa tsa rona li rekisitsoe linaheng le libaka tse fetang 60.
Sehlopha sa Precise se qalile ka 2004, se kenyelletsoeng ke mekhatlo e meraro: Precise New Material Technology Co., Ltd., moetsi oa mono-masterbatch le pre-dispersed pigments e leng Hubei, Chaena; Ningbo Precise New Material, e fana ka ho romelloa ha mebala bakeng sa fiber, filimi, polasetiki joalo-joalo; le Anhui Qingke Ruijie New Material, e 'ngoe ea lihlahisoa tse kholo ka ho fetisisa tsa dae le li-pigment Chaena. Ka kakaretso, re na le mare a 15 a Q/C le bahlahisi ba 30, basebetsi ba 300 ba sebetsang, ba nang le lithane tse 8000 tsa lidae tse hlapollang, lithane tse 6000 tsa mono masterbatch le ho lokisoa ha pigment/pigment pele ho qhalakantsoeng.
Ho qala ka ho romela dae ea solvent le li-pigments tse sebetsang hantle, Precise ha e fetole boitlamo ba rona ho ts'ebeliso ea thepa ea polasetiki ka ho atolosa likopo tsa rona ho fiber ea maiketsetso, filimi le jete ea enke ea dijithale. E le hore re be le litšenyehelo tse ngata, khoebo ea rona e atolosoa ho tloha ho motsoako oa mebala ho ea ho phekolo ea morao-rao, ka ho lumellana ho tloha phofo ho ea ho granule, e le ho phethahatsa morero oa rona: ho fana ka mebala e hloekileng le e bonolo ho e sebelisa lefatšeng.
