Hydrocarbon Resin also knowns as Petroleum Resins,is a kind of '''petroleum Hydrocarbon resin produced by C5 fraction and C9 fraction,by products of petroleum cracking,through pretreatment,polymerization and distillation.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.
