Product Details
Introduction of C9 Hydrogenated Petroleum Resin
C9 Hydrogenated Petroleum Resin is a water-white thermoplastic resin obtained by polymerization and hydrogenation of C9 fraction, a by-product of ethylene cracking, as a raw material.
Since C9 Hydrogenated Petroleum Resin has good thermal stability and good compatibility with EVA, SBS, SEBS, rubber, BOPP, polyolefin and other resins, it is widely used in the fields of hot melt adhesives and pressure-sensitive adhesives.

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 C9 Petroleum Resin? | Resin petroleum, also known as hydrocarbon resin, is a synthetic resin that is derived from petroleum or natural gas. |
| C9 Petroleum Resin vs C5 Petroleum Resin | C5 petroleum resin is an aliphatic resin known for its high viscosity and compatibility with rubber, making it ideal for adhesives and road marking paints. C9 petroleum resin is an aromatic resin with a high softening point, deep color, and excellent chemical/heat resistance, making it suitable for paints, inks, and coatings. |
| What is the C9 Resin price trend? | As of early 2026, the global C9 resin market is showing a mixed trend, with a slightly bearish or stable outlook. Themarket is recovering after a slowdown in 2025, with adhesives and coatings driving long-term growth. |
| What is C9 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. |
