C5/ C9 Copolymerized hydrocarbon resin is a thermoplastic resin. C5/C9 fraction of petroleum by product of decomposition with processing pre-treatment, polymerization and distillation.
C5/ C9 has advantages both of C5 and C9 petroleum resin: low acid value, good miscibility, waterproof, ethanol resistance and chemical resistance, and other characteristics of acid resistance, chemical stability, weather resistance and light aging resistance because of non-polar groups in its structure.
C5/ C9 have good solubility in organic solvents especially in oil solvent, as well as good compatibility with other resins.It also has brittle, increasing viscosity, cohesiveness and plasticity. Generally, it is not used alone, but used as accelerant, regulator and modifier together with other resins.
According to the different C9 content,Shenghong C5/C9 Copolymerized Hydrocarbon Resin have two primary categories:
Acid Value（KOH mg/g）
Adhesives, Rubber compounding, Paint.
