C9 petroleum resin is a kind of thermoplastic oligomer, and its production process will involve treatment process, polymerization process and distillation process, etc. C9 petroleum resin has a relatively low acid value, good miscibility, and water resistance, chemical resistance and ethanol resistance and other advantages, its chemical properties are relatively stable, it can be used as a regulator and modifier in the fields of coatings, paints, rubber and other fields to improve the performance of various products. In many chemical industries, the application effect of C9 petroleum resin is very good, and it has become an indispensable product.

Petroleum resin is a new type of chemical raw material developed in recent years. It has low price, good miscibility, low melting point, water resistance, ethanol resistance, chemical and other properties, and is widely used in rubber, adhesives, coatings, and papermaking, ink and other industries and applications.

Petroleum resin refers to a thermoplastic resin made from the by-products C5 and C9 fractions of petroleum cracking through pretreatment, polymerization, distillation and other processes.
