C9 hydrocarbon resin used in rubber and tires industry.

C9 hydrocarbon resin is a kind of resin produced by 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 solubility, 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.

 This kind of resin used in rubber and tires has good inter solubility with natural rubber and little influence to vulcanization. Putting in it can make the rubber more, adhesive, strength and soft.It is suitable to high quality rubber product such as radial tires.
