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 resistanc because of non-polar groups in its structure.
C5/ C9 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, it is not used alone, but used as accelerant, regulator and modifier together with other resins.
Characteristics:
1) Excellent compatibility with EVA, Rubber, SIS, SEBS, SBS
2)Low molecular weight good heat resistance
3) Excellent peel an tack properties
4) Low volatility and low odor
5) Water resistance
Product Application Field:
C5/ C9 Copolymerized Petroleum Resin can be used in hot melt adhesives, adhesives, rubber and tire fields, especially in radial tire with the effects.
