C9 Petroleum Resin

C9 Petroleum Resin is a thermoplastic resin produced by polymerizing C9 fraction, a by-product of cracking ethylene plant, in the presence of catalyst or copolymerizing it with aldehydes, aromatics and terpenes. Its molecular mass is generally less than 2,000, softening point is less than 150 ℃, thermoplastic viscous liquid or solid. Due to its low softening point and relatively small molecular weight, it is generally not used as a material on its own. Since C9 petroleum resin does not contain polar groups in its structure, it has good water resistance, acid and alkali resistance, weatherability and light aging resistance, good solubility in organic solvents, good compatibility with other resins, and brittleness, tackiness, adhesion and plasticity, and is mainly used in the fields of coatings, rubber additives, paper additives, inks and adhesives, with a large market demand.
