M'mbuyomu, makampani opangira utomoni wa petroleum ankadalira masitolo ogulitsa njerwa ndi matope kuti akulitse msika ngati akufuna kupititsa patsogolo phindu lawo pazachuma. Komabe, Petroleum Resin chifukwa cha nthawi komanso zovuta za malo, kukula kwa msika kunali kochepa.
M'zaka zaposachedwa, Petroleum Resin zapezeka kuti dimers of dicyclopentadiene (CPD) ndi methylcyclopentadiene (MCPD) mu C9 sangagwiritsidwe ntchito bwino, Petroleum Resin kuchititsa kuwononga chuma.
C9 petroleum resin emulsion emulsified ndi zosungunulira ndi emulsifier akhoza kukhala miscible ndi neoprene emulsion kupanga kunja kwa khoma utoto ndi odana ndi dzimbiri utoto ndi adhesion wamphamvu ndi kukana nyengo; kugwiritsidwa ntchito ngati zomangira zomangira zimatha kupititsa patsogolo zokolola.
Kampani yomwe imagwiritsa ntchito ufulu wodziyimira pawokha komanso luso laukadaulo wopanga hydrogenated carbon nine petroleum resin hydrogenation process process zida mosatekeseka komanso bwino kwa masiku 45, Petroleum Resin njira zonse zidatsegulidwa, mtundu wa hydrogenated carbon 9 petroleum resin wafika Mulingo wazinthu zakunja zofananira, Utomoni waPetroleum ukuphwanyatu chinthucho Kudalira zomwe zimatumizidwa kunja. Ukadaulo wopangawu tsopano walandira chilolezo chovomerezeka chapadziko lonse lapansi.
Chiyambireni m'nyengo yozizira, Petroleum Resin msika wapakhomo wa petroleum resin wakumananso ndi "nyengo yozizira" ina.
Kuchokera ku 2004 mpaka pano, m'zaka zapitazi za 9, Petroleum Resin Ndawona kusinthasintha kwa mitengo kuchokera ku C5 zopangira mafuta kupita ku mafuta a petroleum resin. Panthawiyo, zida za kaboni zisanu zinali 3,600 yuan / tani, petroleum Resin resin petroleum resin inali 8,000 yuan / tani,
