Hydrocarbon resin is made from petroleum based feedstocks, like C5, C9, DCPD, or the mixture of these materials. The C5 refers to the aliphatic, and C9 is aromatic, DCPD is dicyclopentadiene. There are different kinds of hydrocarbon tackifier resins. Well, the aliphatic resin is named because they are generally polymers of monomers with five carbons. Basic C5 aliphatic resins have gardner colors between 1.5 to 6 and are mostly used to tackify aliphatic polymers, especially natural rubber. Well, the hydrogenated C5 have been hydrogenated to improve the color and thermal stability actually.

C9 Aromatic Resins are named because they are generally polymers of nine-carbon aromatic monomers. They are based on aromatic feedstocks that undergo very little refining prior to the polymerization of the resin actually. In comparison with C5 aliphatic resin, the color is more dark. This kind of resin is mainly used in EVA-based adhesives, contact adhesive for footwear, printing inks, sealants and paints. If you need flooring adhesives, you are advised to use C9 liquid resins. C9 resins have a distinctive aromatic odor.

C9 resin can be classified into 2 types, pure monomer C9 and hydrogenated C9. The pure monomer C9 is based on aromatic feedstocks that have been highly purified prior to polymerization. This kind of resin is usually stable and in water-white color. The lower softening point types are mainly applied in EVA for book binding adhesives and improve creep resistance in HMA for diapers.

There are also C5/C9 resins that are C5 tackifiers co-polymerized with aromatic monomers. They are excellent tackifiers for use in EVA, SBS, and natural rubber polymers. For more detailed information about hydrocabon resin, you can visit our website www.shqilongchem.com
