C9 Petroleum Resins Specifications:
C9 Petroleum resins is a kind of thermal plasticizing resin produced by C9 fraction, by-products of petroleum cracking, through pretreatment, polymerization and distillation. It isn't a high polymerbat 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 petroleum resins are not used independently, but have to be used together with other kinds of resins as promoters, adjusting agents and modifiers.
Properties and functions of petroleum resins in different application areas petroleum resins are added to paints can increase the final finishes of paints, the adhesiveness of paint films and the hardness. Resistance to acid and alkaline. have very good mutual solubilities with naturalrubber particles, No affect to the sulphurization of rubber. Rubbers added with petroleum resins will increase the strength, adhesiveness and softening property._ Subsequently they will reduce the production cost. fast dry and brightening effects and will increase theprinting property. They can't be transported together with self-flammable materials, strong oxidizers and strong acid. specifications by inspection after one gear. |
