Kare, makambani epetroleum resin aifanira kuvimba nezvitoro zvezvidhinha-nedhaka kuti musika uwedzere kana vaida kuvandudza hupfumi hwavo. Nekudaro, Petroleum Resin nekuda kwenguva uye zvimhingamipinyi zvenzvimbo, musika wekuwedzera saizi yaive shoma.
Mumakore achangopfuura, Petroleum Resin zvakaonekwa kuti dimers e dicyclopentadiene (CPD) uye methylcyclopentadiene (MCPD) muC9 haigone kushandiswa nemazvo,Petroleum Resin zvichikonzera kutambisa zviwanikwa.
C9 petroleum resin emulsion emulsified ne solvent uye emulsifier inogona kusanganiswa ne neoprene emulsion kuita kunze kwemadziro pendi uye anti-ngura pendi ine yakasimba adhesion uye mamiriro ekunze; inoshandiswa sekukanda Binders inogona kuvandudza goho rekukanda.
Kambani inoshandisa yakazvimiririra yakazvimiririra kodzero yezvivakwa zvehungwaru uye tekinoroji yematekinoroji kugadzira hydrogenated kabhoni nine petroleum resin hydrogenation process michina yekugadzira zvakachengeteka uye zvakanaka kwemazuva makumi mana nemashanu, Petroleum Resin ese maitirwo akavhurwa, mhando yeyakaguma hydrogenated kabhoni mapfumbamwe petroleum resin yakasvika mwero wezvakafanana zvigadzirwa zvekunze, Petroleum Resin kutyora zvachose chigadzirwa Kuvimba nekunze. Iyi tekinoroji yekugadzira ikozvino yawana mvumo yenyika yekugadzira patent.
Kubva kupinda munguva yechando, Petroleum Resin musika wepetroleum resin yakazara wakasangana neimwe "chando chinotonhora".
Kubva ku2004 kusvika ikozvino, mumakore apfuura 9 makore, Petroleum Resin ndakaona kuchinja kwemitengo kubva kuC5 raw materials kusvika kune petroleum resin products. Panguva iyoyo, kabhoni shanu zvigadzirwa zvaive 3,600 yuan/ton, Petroleum Resin petroleum resin yaive 8,000 yuan/ton,
