Petroleum resin, also known as hydrocarbon resin, is a key tackifier raw material widely traded in global chemical markets. Accurate CAS numbers are essential for customs clearance, SDS/MSDS preparation, regulatory compliance and product grade verification for overseas buyers.

The most frequently used CAS numbers for petroleum resins include 64742-16-1 for C5 aliphatic petroleum resin and 68131-77-1 for C9 aromatic petroleum resin. Hydrogenated petroleum resins, another popular category, carry their own separate CAS registry entries. It is important to note that CAS numbers alone cannot fully define a resin grade. Different softening points, Gardner color values, melt viscosities and molecular weight distributions lead to different product performances, even under the same CAS number.

Our product portfolio covers C5 resin, C9 resin, C5/C9 copolymer resin and hydrogenated petroleum resin. These hydrocarbon resins deliver excellent tackiness, thermal stability and compatibility with elastomers, waxes and polymers. Typical applications include hot melt adhesives, pressure-sensitive adhesives, traffic road marking paint, printing ink, rubber modification and industrial coatings.

As a professional petroleum resin supplier, we guarantee transparent CAS information, complete TDS and MSDS documents, consistent quality and customized packaging. We support customers to meet import and chemical control requirements across different countries. Please contact us if you need grade datasheets or compliance support.
