Petroleum resin is a kind of thermoplastic resin produced by pre-treatment, polymerization and distillation of C5 /C9 fraction which is a by-product of petroleum cracking. Petroleum resin has the characteristics of regulating viscosity and good thermal stability, the main function is to provide viscosity and wetting effect.

Petroleum resins are generally not used alone, but as accelerators, modifiers, modifiers, and other resins. Petroleum resin is divided into C5 petroleum resin, C9 petroleum resin, C5 /C9 copolymer petroleum resin and hydrogenated petroleum resin according to different raw materials. Different types of petroleum resins have a certain degree of interoperability, in some areas can replace each other, but in various applications also has its own unique.

C5 petroleum resin: low softening point, light color, low degree of unsaturation, and other resins, rubber and other good compatibility; mainly used in pressure sensitive adhesive, hot melt adhesive, road signs paint, synthetic rubber, radial tires and other fields, also used in paint, ink and other fields.

C9 petroleum resin: high softening point, color depth, high degree of unsaturation, good weather resistance, and rubber, SIS, such as poor compatibility; Mainly used in paints, inks and other fields in hot melt adhesives, rubber and other fields also have applications.

C5 /C9 copolymer petroleum resin: both C5/C9 petroleum resin characteristics, softening point is relatively high, compatibility is relatively good; mainly used in hot melt adhesives, synthetic rubber, tires and other fields.
