There are obvious differences in the sources, uses and properties of petroleum resins C5 and C9.


C5 petroleum resin: derived from the C5 fraction produced during petroleum cracking and mainly contains non-aromatic compounds such as isoprene and piperylene.

C9 petroleum resin: derived from the C9 fraction produced during petroleum cracking, mainly containing styrene, methylstyrene, indene, methylindene and other aromatic compounds.


C5 petroleum resin: mainly used for adhesives, pressure-sensitive adhesives, road marking coatings, etc. Due to its high adhesion, good fast tack, and good compatibility with the polymer matrix, it has gradually replaced natural resin tackifiers (such as rosin and terpene resin).

C9 petroleum resin: mainly used in paints, anti-corrosion coatings, etc.



C5 petroleum resin: has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance, chemical stability to acids and bases, and good viscosity adjustment and thermal stability.

C9 Petroleum Resin: Relatively low bonding force. C5 petroleum resin has a small smell, while C9 petroleum resin has a strong smell.

In general, C5 and C9 petroleum resins have their own characteristics in terms of sources, uses and properties. In practical applications, the appropriate petroleum resin type can be selected according to needs.
