Product Description

~*9C Series Copolymerized hydrocarbon Resins are thermoplastic resins, C5, C9 fraction of petroleum by-product of decomposition with processing pre-treatment, polymerization and distillation.
*9C Series Copolymerized hydrocarbon Resins have advantages both of C5 and C9 petroleum resins:
Low acid value, good miscibility, waterproof, ethanol resistance and chemical resistance and other characteristics of acid resistance, chemical stability in acid-bases, adjustment in viscosity, good thermal stability, weather resistance and light aging resistance because of non-polar groups in its structure.
*9C Series Copolymerized hydrocarbon Resins has 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, they are not used alone, but used as accelerant , regulator and modifier together with other resins.

Applications:
A. *9C Series Copolymerized hydrocarbon Resins can be used in hot melt adhesives, pressure sensitive adhesive and so on in adhesives industry . In adhesives Industry, *9C Series Copolymerized hydrocarbon Resins can not only provide better initial cohesiveness, but can also be used like rosin resins to adjust and improve viscosity durability and strength of mixture of glue and resins.
B. Especially in radial tire with the effects of not only increasing adhesion between particles but also improving adhesion between particles and cord
