Product Description

Petroleum resins is a kind of thermal plasticizing resin produced by C5, 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 *******0. 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
A   paints
Paints mainly use C9 petroleum resins, DCPD resins and C5/C9 copolymerized resins with high softening points, 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.
B   Rubbers
Mainly use C5 petroleum resins, C5/C9 copolymerized resins and DCPD resins with low softening points, these kinds of resins have very good mutual solubilities with natural rubber particles, No affect to the sulphurization of rubber. Rubbers added with petroleum 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
