C9 Light Petroleum resin is a kind of thermal plasticizing resin produced by C9 fraction, by-products of petroleum cracking, through pretreatment, polymerization and distillation, It is not a high polymer but a low polymer with the molecular weight between 300-3000. Featured 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 petroleum resins are used together with other kings of resins as promoters, adjusting agents and modifiers.
Product Application Field:
♦ A paints:Paints mainly use C9 petroleum resins with high softening points, petroleum resins areadded to paints can increase the final finishes of paints, the adhesiveness of paint films and the hardness. Resistance to acid and alkaline.
♦ B Rubbers:Mainly use C5 petroleum resins with low softening points ,these kinks of resins have very good mutual solubilities with natural rubber particles, No affect to the sulphurzation of rubber. Rubbers added with pertroleum resins will increase the strength, adhesiveness and softening property.
♦ C Adhesives:Petroleum resins have very good adhesiveness, they can increase the adhesiveness of adhesives, resistance to acid, alkaline and water. Subsequently they will reduce the production cost.
♦ D Printing inks:Usually , The C9 petroleum resins with high softening point are used for printing inks, they have color spreading ,fast dry and brightening effects and increase the printing property.
♦ E Other: Petroleum resins have certain unsaturation property and can be used as paper glutting agent, plastic modifiers etc.
