Cov tawg C9 feem ntau muaj unsaturated aromatic hydrocarbon tebchaw xws li vinyl toluene, indene, methylstyrene, Petroleum Resin thiab lwm yam. C9 yog nkag rau hauv C5 tivthaiv, Roj av Resin thiab compatibility ntawm C5 / C9 roj av resin tau los ntawm ob copolymerization ntawm cov roj av. Polar polymers tau txhim kho, Petroleum Resin piv txwv Nws tuaj yeem txhim kho kev sib raug zoo nrog EVA resin. Vim yog cov yam ntxwv ntawm ob qho tib si aliphatic thiab aromatic resins, Petroleum Resin muaj zoo solubility nyob rau hauv ntau yam ntawm cov kuab tshuaj thiab txhim kho lub tshav kub tsis kam thiab huab cua tsis kam ntawm aliphatic resins.
C5 / C9 roj av resin yog tsim los ntawm cov tshuaj tiv thaiv ntawm chav tsev kub. Kho qhov sib piv ntawm C5 thiab C9 tuaj yeem tau txais resins nrog cov khoom sib txawv. Qhov siab dua qhov piv ntawm C9, Petroleum Resin ntau dua qhov muag muag thiab viscosity ntawm cov resin thiab qis dua tus nqi bromine. Cov txheej txheem tsim khoom ntawm C5 / C9 copolymer resin, Roj av Resin tshwj tsis yog qhov yuav tsum tau nce C9 feem ua ntej kom tau txais C9 feem, Petroleum Resin cov txheej txheem yog roughly tib yam li C5 aliphatic petroleum resin.
Hydrogenated petroleum resin: Nrog rau kev siv dav ntawm cov nplaum nplaum nplaum thiab cov nplaum nplaum, Roj Hmab Resin xav tau ntau dua yog tsim rau cov xim ntawm cov roj av resins, Petroleum Resin tshwj xeeb tshaj yog cov ntaub qhwv (tso pov tseg) thiab cov khoom huv si yuav tsum tau pob tshab thiab tsis muaj xim roj av. Hydrogenated petroleum cob tau los ua. Lub hydrogenation ntawm resin yog kom yaj cov resin nyob rau hauv ib qho inert hnyav thiab hydrogenate nyob rau hauv cov kua theem. Feem ntau siv hydrogenation catalyst yog nickel-based catalyst.
