Introduction of C5/C9 Copolymer Petroleum Resin CAS 68131-77-1
The main raw material of C5/C9 Copolymer Petroleum Resin is cracked C9, which mainly contains unsaturated aromatic compounds such as styryltoluene, indene, and methylindene. C5 is introduced into C9, and the C5/C9 copolymer petroleum resin obtained by copolymerization modification has improved compatibility with EVA due to the characteristics of both aliphatic resin and aromatic resin; at the same time, it also has good solubility in a variety of solvents.
C5/C9 Copolymer Petroleum Resin can be used in hot melt adhesives, tires and rubber products, and can be used as a substitute for terpene resins, rosin glycerol esters, etc.

What are the different types of C9 petroleum resins?
C9 petroleum resin, also known as aromatic petroleum resin, is classified into thermally polymerized, cold-polymerized, and tar-based types.
Frequently Asked Questions
| Question | Answer |
| What is C5/C9 Copolymer Petroleum Resin? | C5/C9 copolymer petroleum resin is a low molecular weight thermoplastic hydrocarbon resin, copolymerized from C5 (aliphatic) and C9 (aromatic) fractions, byproducts of petroleum cracking. It combines the high viscosity of C5 resin with the high softening point and excellent compatibility of C9 resin, making it a versatile tackifier and modifier. |
| what is petroleum resin? | Petroleum resin (or hydrocarbon resin) is a low-molecular-weight thermoplastic resin produced from petroleum by-products (C5 or C9 fractions) through catalytic polymerization. |
| What is petroleum resin used for? | Petroleum resins (C5/C9 hydrocarbon resins) are multifunctional tackifiers, adhesives, and modifiers, mainly used in hot melt and pressure-sensitive adhesives, tire rubber formulations, industrial coatings, printing inks, and road marking coatings. |
