General introduction to petroleum resins

Petroleum Resins,including C5 petroleum resin,C9 petroleum resin,C5/C9 Copolymerization petroleum resin,DCPD petroleum resin and hydrogenated petroleum resins,also knowns as Petroleum Hydrocarbon Resin,is a kind of Hydrocarbon resins produced by C5 fraction and C9 fraction,by products of petroleum cracking,through pretreatment,polymerization and distillation and other a series of industrial process.It isn't a high polymer but a low polymer with the molecular weight between 300-3000.Featared by acid value,easy mutual solubilities,resistant to water,resistant to ethanol and chemicals.It has the chemical stabilizing property to acid and alkaline,viscosity adjusting and thermal stabilizing.Generally,the resins are not used independently, but have to be used together with other kinds of resins as promoters,adjusting agents and modifiers in Paint, Ink, Coating,Adhesive,Rubber Tyre,asphalt in a wide applications.It has become one of the part of our life.
